[Bug 238572] New: SCSI Subsystem Locks-up Machine
https://bugzilla.novell.com/show_bug.cgi?id=238572 Summary: SCSI Subsystem Locks-up Machine Product: openSUSE 10.2 Version: Final Platform: x86 OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: jim@edwardsj7.com QAContact: qa@suse.de My system has the root, "/", and "/home" directories on two different SCSI drives on the same chain of an Adaptec 29320 (U320) card and they are using the AIC79xx driver version 3.0. From time to time the system will cease to function and the SCSI activity indicator LED will stay on at 100% (usually it only flashes very briefly) and the machine becomes unresponsive. Maybe after a long time it will seem to return, but really the SCSI drives are off-line and even a restart fails back to what looks like an "init 3" screen with "login" displayed, but nothing is accepted. A system hard RESET, or power off and on, is required to restore functionality. The ensuing reboot displays a large number of transactions being replayed for the "/" RFS, 800+ is not unusual, but nothing for the ext3 (when it was RFS it had some transactions). It seems that this lock-up is triggered by things that try to move a lot of data over the SCSI bus, like "mkisofs" or some other large file transfers. Moving "/home" to an IDE drive did not help. "/" is on an RFS version 3.6 partition and "/home" is on an ext3 partition (it was RFS, and changed to ext3 with no effect). The same system hardware (AMD Athlon XP 2500+ etc.) has been running Suse 9.0 successfully with no such problems, and still can, so it seems to me to be likely to be related to the newer drivers (version 9.0's are much older, version 1.3.something, I think), possibly in association with RFS ???

https://bugzilla.novell.com/show_bug.cgi?id=238572 ------- Comment #2 from jim@edwardsj7.com 2007-01-25 16:12 MST ------- OK, there are tons of errors sequential from the SCSI subsystem, but they are associated with a DVD drive that is on the other channel of the controller card and only occur once. I am sure they are not associated with the lock-ups :-( The two SCSI drives are denoted sdb and sdc and there are no error messages about sdc (where "/", RFS, is located) or sbd (where "/home", ext3 is). SMART monitoring is enabled on the drives and it says they are healthy. Scanning the log file shows some cases where there appears to be an abnormal start, based upon syslog-ng starting, without an associated "going down" on the line before. Here are a couple of the sets of lines that are like this :- Jan 18 21:34:20 linux smartd[4125]: Device: /dev/hda, SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 54 to 55 Jan 18 21:34:20 linux smartd[4125]: Device: /dev/hda, SMART Usage Attribute: 195 Hardware_ECC_Recovered changed from 54 to 55 Jan 18 21:47:50 linux syslog-ng[2887]: syslog-ng version 1.6.11 starting Jan 19 16:30:47 linux kernel: klogd 1.4.1, ---------- state change ---------- Jan 19 16:38:14 linux smartd[4122]: Device: /dev/hda, SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 54 to 53 Jan 19 16:38:14 linux smartd[4122]: Device: /dev/hda, SMART Usage Attribute: 194 Temperature_Celsius changed from 32 to 36 Jan 19 16:38:14 linux smartd[4122]: Device: /dev/hda, SMART Usage Attribute: 195 Hardware_ECC_Recovered changed from 54 to 53 Jan 19 16:53:28 linux syslog-ng[2929]: syslog-ng version 1.6.11 starting As you can see the log entry prior to the restart was not immediately before. Usually I did not allow the system to hang for a long time once I realized what was going on ! I think that as the SCSI drives went off-line there was no record of what was happening :-( When I get a chance I have to look and see if I have a suitably sized, unused partition on either an IDE drive, or the other SCSI drive, to move "/" to as a test.

https://bugzilla.novell.com/show_bug.cgi?id=238572 ------- Comment #4 from jim@edwardsj7.com 2007-02-06 16:06 MST ------- I would love to send you a log file, but once the SCSI system locks-up all writing to anything stops, so the logs show nothing. The issue is very hard to understand, it happened twice yesterday almost immediately after booting and then not for the rest of the evening. My feeling is that heavy traffic on the SCSI bus is what provokes it, but it is only a feeling I have no hard evidence to back it up. For example I can almost guarantee to cause a lock-up by trying to make an "iso" file from my /home/USER directory (~2.4GB), which takes data from a SCSI drive and then sends the iso image back to the same drive ... Lots of traffic ! During a re-boot the zen update software runs and it accesses the drives a lot, maybe if I am adding traffic to that by starting applications (browsers in yesterday's case) it is overloaded. Maybe the timing in the driver is too aggressive ? As I said Suse 9.0 has no such problem with the same hardware, but its AIC79xx driver is much older. In fact I see that Adaptec has only up to a version 2 driver for 2.6 kernels, while 10.2 loads a version 3 ??? Could I downgrade the driver to the Adaptec one ? Anyway, if there is nothing that can be done that's it. I will wait in the hope that there will be an update to the driver that will fix the issue by coincidence ;-) Jim -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

At one point I was getting one or more a day some days, now I am often going several days without any misbehaviour (although last night it crashed and trashed a VPN configuration file, the first data loss I can attribute thanks to ext3 and RFS). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I checked and the new kernel had replaced the SCSI drivers with the same ones as before patching, so I have reapplied the patch and we'll see what happens. I think it will get better again, but still not perfect.

I found a sure-fire way to get a lock-up, that was to install the latest version of Nero (CD/DVD Writer) and try running it. It gets as far as the window saying it is "Scannig for Drives" and freezes the machine with the SCSI active LED on, requiring a reboot to recover ! With Suse 9.0 Nero would take my SCSI converted IDE DVD-RAM drive (LG GSA-4163 with Acard 7722) off line until a reboot, but the rest of the machine would continue to work. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

After 20 minutes no lock-ups, but that is hardly a valid test as it would go for days on end without doing so. Other points :- - Whenever the kernel is updated I have had to reapply the patch, as expected. - After installing the latest HAL update the incidence of lock-ups seems to have increased. That might help go along with the Acard being a contributing factor, as the HAL probably does not know what it is or even if it is there ! I'll re-post in a week if I see no more lock-ups, or sooner if I do. I can later move the DVD to an IDE channel, there is an unused master connector right there by it (I just prefer SCSI) :-) I have downloaded Nero for Linux 3.0.0 and it does not lock-up scanning, but of course now it has no DVD to write to (it can see my old Plextor SCSI CD-RW drive):-( Jim -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ---

As I wasn't watching at the time I don't know whether it had the usual symptoms of the SCSI activity LED staying on for a long time and then going off, leaving the system unusable, or not. It was certainly unusable with even the cursor locked ! My feeling is that this was a different lock-up, but I cannot guarantee my feeling is accurate, as it is a long time since I left a lock-up to go to its conclusion, usually I have been hitting the RESET button as soon as I see the SCSI LED on ! So looking good, but not yet guaranteed :-) I will keep watching ! If it is the Acard+DVD it is odd that it was perfectly stable under Suse 9.0, and it was. Not that I'm going back to 9.0 to get that working again ! If the Acard is the cause is it likely that there can be a fix worked out that will allow it to work ? The original patch goes a lot of the way towards making it stable :-) In the meantime I bought a couple of 4GB USB memory sticks as back-up media, although the data transfer is slower than to DVD-RAM.

Still no lock-ups :-) To the system the ACARD+ATAPI-DVD appear as a SCSI DVD drive (MMC compatible), wide 68 pin connector (80Mbps), which of course does not exist as a real product, and the driver that is loaded is the aic79xx. This is also used by the SCSI hard drives containing the OS and /home directories which are on the same SCSI chain (which is probably why the lock-up is hard). There are two CD drives and a MagnetoOptical drive on a second SCSI chain which is narrow (and not compatible with the ACARD). Remember that patching the aic79xx driver significantly improved the situation, which sort of implicates it as part (or all ?) of the problem. The issue occurs whether the DVD is in use or not (maybe it's the auto insert polling that causes it ?) ! Adaptec has its own 2.6 kernel drivers, but I have not tried the, as losing SCSI would disable the system and they are for version 10 (no .X) and stated for RAID enabled, which I do not have :-( Jim -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

About 2 weeks ago I rearranged my SCSI chains to re-include the Acarded DVD drive. This time I put the Acard on its own wide (68 pin) single-ended chain, with the hard drives remaining on the LVD chain and the other drives on a narrow single-ended chain. I figured that if I got a lock-up now, with the hard drives separated, there might be a log file written :-) However, what has actually happened is no lock-up's at all ! It seems that the Acard (80Mbps LVD )did not like sharing a chain with the hard drives (160Mbps LVD) when running under 10.2 (there was never a problem with 9.0). I will continue to watch what goes on, and if there are any future problems I will come back ! There is a kernel update to install, but I am not happy to do it as it requires the nVidia driver to be reloaded and probably the aic79xx repatching ... Too much messing around for me to rush to do !

The second extract is the area just before I give up and try to shutdown the machine. Does the DMA in 10.2 work very differently to that in 9.0, so that the data is sent out much more rapidly ??? My next step should be to move the DVD recorder to its native ATAPI/IDE interface.

It's actually a mainline bug now (kernel.org bugzilla #5921), so we should continue using that. Again, really sorry. I really appreciate your help here and I would love to debug this properly. But I'm swamped with other bugs right now and can't really do anything in a timely manner here. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I will shortly be moving over to 64 bit 11.0, so maybe there the fun will start again ! I will now try to remember to watch the kernel track.
