This has happened twice since the last kernel update. Kernel is 2.6.8-1.521. Intel(R) Pentium(R) 4 CPU 2.40GHz 1 GB ram IDE Drives We are having the same problem here. It has gotten worse since updating to 2.6.8-1.521. Daily, usually hard, reboots are required (on a production system!). System hangs/lockups are not predictable, but are likely exacerbated by running xfs_dump. (I am going to try to downgrade the kernel to see if that helps.) This may or may not be related, but we are also having trouble dumping to our SCSI tape drive (logs show many SCSI errors). I will not include a log file unless requested, as it would seem redundant with what is already submitted. THIS IS A SERIOUS BUG!!! The owner should change this to HIGH priority! Marco: Is this still happening for you with current rawhide kernels ? Brendan: Your oops is completely different and unrelated to this bug. It's also tainted with proprietary modules. Please try to repeat with a current kernel without those loaded, and file a seperate bug report if it persists. Richard: can you also test with a current kernel, and paste the oops you are seeing if its still reproducable. Thanks. Thanks for your answer Mr Dave Jones. Sorry I can't understand "rawhide kernels" my kernel is a "vanilla" version 2.6.8-1.521 (yum update) with the latest updates, my server still freeze and is unstable (two or three reboots per week) I think downgrade FC1 or change to Debian Sarge :( Here is a log file snippet from last August. I THINK I was running the most current kernel then. Since then, I downgraded a tad and applied a custom patch on the web which dealt with xfs software deficiencies. using linux kernel 2.6.5-1.358: Aug 17 17:20:17 bob kernel: printing eip: Aug 17 17:20:17 bob kernel: 4298030e Aug 17 17:20:17 bob kernel: *pde = 00000000 Aug 17 17:20:17 bob kernel: Oops: 0000 [#1] Aug 17 17:20:17 bob kernel: CPU: 0 Aug 17 17:20:17 bob kernel: EIP: 0060:[<4298030e>] Not tainted Aug 17 17:20:17 bob kernel: EFLAGS: 00010206 (2.6.5-1.358) Aug 17 17:20:17 bob kernel: EIP is at xfs_iget_core+0x4e/0x42b [xfs] Aug 17 17:20:17 bob kernel: eax: 00004000 ebx: 4040a038 ecx: 00004000 edx: 00000000 Aug 17 17:20:17 bob kernel: esi: 000c0c4f edi: 00000000 ebp: 40f31000 esp: 35ab6d2c Aug 17 17:20:17 bob kernel: ds: 007b es: 007b ss: 0068 Aug 17 17:20:17 bob kernel: Process xfsdump (pid: 15597, threadinfo=35ab6000 task=412aaeb0) Aug 17 17:20:17 bob kernel: Stack: 000008d0 39e4fb00 40770200 00000000 00000000 00000000 08e9bc80 0000400 0 Aug 17 17:20:17 bob kernel: 08e9bc9c 08e9bc80 00000008 40f31000 42980774 000c0c4f 00000000 00000008 Aug 17 17:20:17 bob kernel: 35ab6dd4 00000000 00000000 00000000 00000000 000c0c4f 00000000 00000000 Aug 17 17:20:17 bob kernel: Call Trace: Aug 17 17:20:17 bob kernel: [<42980774>] xfs_iget+0x89/0x124 [xfs] Aug 17 17:20:17 bob kernel: [<42986f7a>] xfs_bulkstat_one+0x112/0x551 [xfs] Aug 17 17:20:17 bob kernel: [<429880fd>] xfs_bulkstat_single+0x37/0xbf [xfs] Aug 17 17:20:17 bob kernel: [<4296d16c>] xfs_da_read_buf+0x2b/0x31 [xfs] Aug 17 17:20:17 bob kernel: [<4296d6a6>] xfs_da_brelse+0xb2/0xf2 [xfs] Aug 17 17:20:17 bob kernel: [<02135342>] follow_page+0xda/0xe5 Aug 17 17:20:17 bob kernel: [<0213f1ba>] rw_vm+0x1ce/0x1ea Aug 17 17:20:17 bob kernel: [<429a2f69>] xfs_ioc_bulkstat+0xe0/0x15c [xfs] Aug 17 17:20:17 bob kernel: [<429a2a82>] xfs_ioctl+0x303/0x680 [xfs] Aug 17 17:20:17 bob kernel: [<429a1dac>] linvfs_readdir+0x1c1/0x1cf [xfs] Aug 17 17:20:17 bob kernel: [<0214edcd>] filldir64+0x0/0x12e Aug 17 17:20:17 bob kernel: [<02135342>] follow_page+0xda/0xe5 Aug 17 17:20:17 bob kernel: [<0213f1ba>] rw_vm+0x1ce/0x1ea Aug 17 17:20:17 bob kernel: [<429a1e42>] linvfs_ioctl+0x18/0x22 [xfs] Aug 17 17:20:17 bob kernel: [<0214ea0e>] sys_ioctl+0x1f2/0x224 Aug 17 17:20:17 bob kernel: Aug 17 17:20:17 bob kernel: Code: 8b 51 3c 8b 41 38 39 fa 0f 85 ec 00 00 00 39 f0 0f 85 e4 00 Aug 17 17:23:14 bob kernel: <4>pagebuf_get: failed to lookup pages Aug 17 17:23:14 bob kernel: pagebuf_get: failed to lookup pages Aug 17 17:23:17 bob last message repeated 6 times more (complete cycle): Aug 29 04:02:04 bob syslogd 1.4.1: restart.

the 2.6.9 based update for FC2 released today. richard, your oops is also completely unrelated (its XFS related). Please file a seperate bug (try the latest kernel update also -- it has various xfs fixes). Sorry Mr. Dave, I needed to downgrade to FC1, because this server is my production server. FC1 is much more stable to me, server is on-line since Nov/07/2004 with just one reboot until today :-) I have other identical server (backup), but is not possible to test in the same conditions (same users, link, load ...) Thanks for your efforts. Dave: I submitted bug # 139450 with reference to XFS crashes in kernel 2.6.9-1.667 not long ago. It's pretty bad. (Feel like taking it on, too?) I had also submitted somewhat related bugs 133424 and 130729 quite some time ago. I have been running (well, limpng along with) a patched version of 2.6.5-1.358 which still crashes, but does so less frequently. marco, if you get a chance to test the latest kernel and this is still a problem, please reopen. otherwise, theres not really much I can do. everyone else, I'll deal with your issues in their seperate bugs. |
