https://bugzilla.novell.com/show_bug.cgi?id=409484 Summary: ata frozen triggered by file transfer over network Product: openSUSE 11.1 Version: Factory Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: nove8624@martinb.com QAContact: qa@suse.de Found By: Customer On openSUSE 11.0 I get repeated log messages about ata frozen but this only happens after being triggered by traffic to and from the ethernet. (on 10.3 it happened without this trigger). here is the history: I have bought a new computer (has ASUS P5M-MX motherboard which uses nForce 610i(MCP73V) chipset and Intel E4600 CPU). when I installed openSUSE 10.3_64 I found the computer was occasionally freezing when say starting a program or shutting down the system. When I checked the system log I found a sequence of messages like this was repeating all the time: Jul 12 09:14:28 suse110 kernel: ata5.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen Jul 12 09:14:28 suse110 kernel: ata5.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 Jul 12 09:14:28 suse110 kernel: cdb 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jul 12 09:14:28 suse110 kernel: res 40/00:03:00:00:00/00:00:00:00:00/a0 Emask 0x4 (timeout) Jul 12 09:14:28 suse110 kernel: ata5.00: status: { DRDY } Jul 12 09:14:28 suse110 kernel: ata5: soft resetting link Jul 12 09:14:28 suse110 kernel: ata5: nv_mode_filter: 0x701f&0x701f->0x701f, BIOS=0x7000 (0xc0000000) ACPI=0x701f (60:600:0x13) Jul 12 09:14:28 suse110 kernel: ata5.00: configured for UDMA/33 Jul 12 09:14:28 suse110 kernel: ata5: EH complete I therefore upgraded to openSUSE 11_64, this appeared to fix the problem, however I have found that these messages can get triggered on this version (on SUSE 11 they only happen after being triggered on 10.3 they happen all the time). Once they are triggered they then continue continuously until I shut down the system. The only thing that seems to trigger these log messages is to mount a network (ethernet) drive: mount.cifs //192.168.0.4/share /mnt/buffalo -o username=guest and then copy a directory between the network drive and my (sata) hard drive. As soon as I start the copy the messages start and continue even after the copy has completed until I shut down the system. I have not found anything else that triggers the log messages, for instance, copying a directory between the sata disk and a usb drive does not cause any problems nor does copying directories within the sata disk. I don't think it is a hardware problem with the hard drive because I used a different physical drive when I switched from 10.3 to 11.0. PS - I can't get the built in nForce chipset ethernet port to work so I am using a seperate PCI card for ethernet. -- 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.
