[Bug 350980] New: The system stops doing things till I press a key or move the mouse: every things halts.
https://bugzilla.novell.com/show_bug.cgi?id=350980 Summary: The system stops doing things till I press a key or move the mouse: every things halts. Product: openSUSE 10.3 Version: Final Platform: i686 OS/Version: openSUSE 10.3 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: robin.listas@telefonica.net QAContact: qa@suse.de Found By: --- This is very weird. Sometimes, the system simply stops "working". Doesn't crash, simply all tasks seems stopped. Nothing refreshes in the display. The clock stops. A script running a loop in a console: #!/bin/bash while true ; do # date +"%T" | tee -a /home/cer/marca.log date +"%T" >> /home/cer/marca.log sleep 1 done stops as well. Then, as soon as I move the mouse or touch a key (shift, for instance) everything continues and the clock jumps some seconds or minutes to the correct time. I have tried several things, as discussed in the "opensuse" mail list (<http://lists.opensuse.org/opensuse/2007-12/msg01780.html>). No effect. - check the desktop for powersave features - nothing, and there is nothing configurable that would kick in in seconds of no user activity. - pass cpufreq=no as a boot argument --> no good. - Recompile the kernel with "NO_HZ" --> even worse (this is the current state). I will recompile again to undo. And more things I forgot, but you can read the whole story in the mail list or the link above. Sometimes, very random, the system stops completely and does not respond to keyboard, but it awakes when I boot another PC, which I think tries to connect or ask for a service (ntp or dns). My current hack is to leave my router continuously pinging me. My guess is that the pings cause the network card to interrupt the kernel, so it keeps awake. Keyboard or mouse also provokes interrupts. I'm not sure about usb activity. This might be related to other bugs reported by me, I don't know (spamd timeout?) I have been "playing" with the clock (Bug 344356 and a new one not reported yet). The thing is that the kernel defaults to using "acpi_pm" clock and this one misses whole minutes. I have to force use "tsc" (which kernel disabled at boot). jiffies crashes. -- 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.

Could you add this line:
cat /proc/interrupts >> /home/cer/marca.log
Done. Today of all days it did not want to cooperate being lazy while I was looking: I guess it knew you were waiting and behaved naughtily. I had to stop mail fetch, ntp daemon, and wait for a minute in several tries, but at last I got it. Search for the time mark "=====> 01:35:15" in the attached file: it jumps to "01:35:43", almost half a minute stopped. There are a few smaller jumps, like "01:32:46..48", "01:33:55..57"; ah, another big one: 01:34:31..01:35:06". A one second jump could be doubtful, but a half a minute one I suppose not. I don't know what you are looking for, but the timer interrupt seems to be ticking :-? -- 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.

How can that be? If they are still 19.2 ticks/second, I should have had 537 ticks. I don't know how the timer works in linux, but I assume that, as the clock shows the correct time, the system uses TSC to estimate the lost interrupts correctly. Is that so? Now, questions... can this be a hardware problem and the timer chip doesn't produces the interrupts? However, in the test the other day with 10.2 there were no symptoms. Is the kernel reprogramming the chip to go slower? Is the kernel ignoring the interrupts? The only thing I can do, as I lack the knowledge of kernel internals, is to try again in 10.2 and measure the ticks over a period. Do you want me to try that? Note 1: This thing must be related to Bug 350981 Note 2: These days I'm using my personalized kernel, instead of the default suse kernel I used the other day for testing (which has the same symptoms).

First time in one or two months. I hesitate to restart it again in nohz=off mode, I hope you understand that. I had also a warning during boot in this mode: first time it stopped during the network start phase, and I rebooted it (I thought the adsl might be down just at that moment). The second time it slowed for a few seconds there, then went on, so I didn't give it much thought. But seeing that it crashed/locked later when attempting to hibernate, all I can say is that the nohz=off mode causes my computer to be unstable. I don't remember it to be unstable when I selected this option at kernel compile time, though... And now I'm really off to sleep. You don't see it in the bugzilla log, but here it is 4:35 AM.

It recovered fine after hibernation. I thought the computer was a bit slow. I went to tty1 ([ctrl][alt][F1]). I typed [Alt][Left] to see the text console dedicated to output messages from the hibernation process: it only showed the single line "resuming..." or something similar. I then continued typing [Alt][Left], a process that would normally get my to the tty10 after some keys, and... the screen was zipping past with messages so fast I couldn't read them, something about an unhandled interrupt. The keyboard locked: I couldn't even toggle the [bloq num] light, a good indicator of a strong lock or crash. I tried pinging, no response. I had to hit the power off button.

Is that two different tests, or one test with both parameters? As to "noapic" I already did, see #15. No good. Do you expect different results with this kernel?

a) noapic
The boot "feels" slow. No "laziness" in the brief test (brief because I didn't go for a coffee to let it time to be lazy). Hibernate works. It does work better. There is this imprecise feeling of being slow, though. I'd have to use a chronometer to time the boot to make sure.
b) irqfixup
I used "apic irqfixup" The boot stopped for ±30" on the line: Starting udevd udevd-event[1691]: node_symlink: device node '/dev/rtc0' already exists, link '/dev/rtc' will not overwrite it No idea why.

I want to, but I can't. For two weekends I haven't been able to upgrade factory because the OSS repo was broken. Now that's been solved, but it is a 1.4 GiB download that takes a minimum of 4 hours to do, actually 8 hours, meaning that the repo has changed again while I try to update... so, hopefully, I will not be able to upgrade my factory till saterday afternoon.

Finally, I have been able to update factory, and I have run a test. I unplugged the network, left my marker script running, and went away for a cup of tea and a stroll. Twenty minutes later, I detected no "laziness". The screen saver had kicked in, beagle had finished, and the script didn't appear to have logged any problem. So far so good...

Have you already searched for a BIOS update?
No, because: - this machine is from about 2001 (P-IV @ 1800Mhz) - it is a kernel issue. It happens only with certain suse versions and not with anothers, there is nothing wrong with the machine. OpenSUSE 11.0 was working fine till the last security kernel update. All versions till and including 10.2 worked fine, 10.3 was the first one to show this problem. Anyway, I did search for a bios update years ago. There is one for the other bios make, not mine.
Please also attach dmidecode and best also hwinfo to get an even better idea what machine we have.

It happens only with certain suse versions Ok, I think I got it, sorry about that.
Let's try to limit this to as less patches as possible, then try out the ones that look guilty. This 11.0 kernel was the first which did not work: 2.6.25.18-0.2-pae Did you do upates before, can you remember the last working kernel? For 10.3 all kernels (you tested) were broken. 10.2 and before worked well. This is all about i386-pae kernels or did you also try x86_64 or i386 without -pae support kernels? -- 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.

Don't worry, this bug has a long story.
Let's try to limit this to as less patches as possible, then try out the ones that look guilty.
This 11.0 kernel was the first which did not work: 2.6.25.18-0.2-pae
Correct.
Did you do upates before, can you remember the last working kernel?
I did all the updates offered by Yast Online Update. I don't remember which one was the previous kernel, but it has to be the previous one in the update server. Perhaps the info is in y2logRPM - yes, here: nimrodel:/var/log/YaST2 # grep kernel-pae- y2logRPM 2008-09-09 22:53:16 kernel-pae-2.6.25.5-1.1.i586.rpm installed ok 2008-09-10 11:44:16 kernel-pae-2.6.25.11-0.1.i586.rpm installed ok 2008-09-11 20:56:28 kernel-pae-2.6.25.16-0.1.i586.rpm installed ok 2008-10-30 02:14:24 kernel-pae-2.6.25.18-0.2.i586.rpm installed ok So, this kernel was installed on 2008-10-30, but I didn't notice the problem earlier because I had a lot of network activity (from 08-11-01 to 08-11-11), and this produces interrupts which keep awake the machine. And grepping for the string "failed after 300 secs" in the warn log, which is the tell-tale, I first see it on Nov 19 15:19:40 I also see I installed a bunch of things on Nov 12, but nothing on the 19th, or at least nothing I can think interesting. I could attach if you want the list with dates, produced by: rpm -q -a --queryformat "%{INSTALLTIME}\t%{INSTALLTIME:day} \ %{BUILDTIME:day} %-30{NAME}\t%15{VERSION}-%-7{RELEASE}\t%{arch} \ %25{PACKAGER}\n" | sort | cut --fields="2-"
For 10.3 all kernels (you tested) were broken.
Yes, as far as I remember. At least, we couldn't find anything that worked. I played recompiling kernels, too. Most of it is logged in this Bugzilla and related ones. Maybe later I can dig out the numbers, the history of this problem.
10.2 and before worked well.
Right.
This is all about i386-pae kernels or did you also try x86_64 or i386 without -pae support kernels?
Well, 10.2 and 10.3 were non pae, pae started to be shipped with 11.0, afaik. This machine is 32 bits, so x86_64 is out of the question. Another detail I remembered: [Bug 426592] clocksource 'acpi_pm' looses time. So I'm forcing the TSC clocksource; I think I have been doing that since 10.3 -- 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.

So, if you want me to test this bug with the above experimental kernel (in my test partition), I'll try. If not, we'll have to wait till 11.2. And no, before you ask: I can not install factory, because that's the 11.1 test partition. -- 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.
