| |
I'm having a problem with 2.6.0-test10 that may be of interest to someone.
I am currently in the process of upgrading to test11, and I will report any changes in behavior if this draws any attention.
I used the outline described in linux/REPORTING-BUGS. If you need any more info please let me know. I am not on the linux kernel mailing list, but I do read the archives. If you want a faster response, please cc me on your reply. Thanks,

[1.] 2.6.0-test10 BUG/panic in mpage_end_io_read
[2.] I have an xfs raid5 array, too which I am trying to copy a bunch of backup folders from half of a failed raid 1 array. After booting, the first two directories copy OK, but on the third one I get either a BUG or a panic every time. It does not matter if I do a cp -a * <dest> or cp -a <dir1> <dir2> <dir3> <dest> or cp -a <dir1> <dest>, wait a while, then copy another directory, etc. No matter what, it seems to always fail on the third directory. Also, the size of the directories copied does not seem to matter. The sizes range from a few megabytes to a few gigabytes, but the third one causes a BUG or panic every time. If I get a BUG, I am unable to communicate with the array anymore at all. All processes that I start which try to communicate with the array (umount, mount -o remount, xfs_check, mdadm) will freeze and cannot be killed. Every time it fails I have to reboot and my array must be rebuilt, which takes about 1.5 hrs of pretty solid hdd activity, so it's kind of painful for me to reproduce this. I keep accidentally reproducing it while I"m trying to copy my data over. While the array is rebuilding I get DMA errors from the hdds attached to the Promise PDC20269. They are part of the raid5 array. In my experience, hdds that are going bad spew out a lot of DMA errors, and usually pages at a time. I'm getting these errors intermittently, with 3-20 minutes between errors. These hdds are brand new, btw.

[5.] I have a copy of the BUG, as well as part of the panic call trace that I typed in by hand on another computer. I tried to check it as best I could, but I may have made a mistake typing it in. ---------------------------------- BUG ------------------------------------ kernel BUG at mm/filemap.c:332! invalid operand: 0000 [#1] CPU: 0 EIP: 0060:[<c0130f4a>] Not tainted EFLAGS: 00010246 EIP is at unlock_page+0x1a/0x40 eax: 00000000 ebx: c1083b08 ecx: 00000017 edx: c1500400 esi: c1500cf4 edi: 00000001 ebp: 00000003 esp: dfcc1f0c ds: 007b es: 007b ss: 0068 Process md0_raid5 (pid: 17, threadinfo=dfcc0000 task=dfcdd2d0) Stack: dffd2e34 cbe5f540 c016201e cbe5f540 dfbcd298 ffffffff dfbcd298 c02a2f75 cbe5f540 00000000 00000000 dfbcd298 dfd20b00 dff7ae00 dfd20b08 c17f872c c17f8764 00000000 dff7ae74 00000000 00000002 00000001 00000004 ffffffff Call Trace: [<c016201e>] mpage_end_io_read+0x5e/0x80 [<c02a2f75>] handle_stripe+0x9e5/0xb30 [<c02a341c>] raid5d+0xec/0x110 [<c02a9af9>] md_thread+0xf9/0x140 [<c02a9a00>] md_thread+0x0/0x140 [<c0119ea0>] default_wake_function+0x0/0x20 [<c010725d>] kernel_thread_helper+0x5/0x18
