Today I merged mm-sources-2.6.0_beta3-r2, built it with the same config. Now, at boot up when checking the reiser journal, reiserfsck 3.6.11 segfaults, and I am asked to enter the root password to check the filesystem manually (it also segfaults). I type "exit", and the bootup goes on as usual. Then, in gnome, I tried reiserfsck on another partition. It segfaults. I tried to rebuild reiserfsprogs 3.6.11, it doesn't help. Everything was working fine with mm-sources-2.6.0_beta3-r1.
Could you please give the output of 'strace reiserfscheck'? [emerge strace]
Created attachment 16082 [details] strace reiserfsck output Ok, I remerged reiserfsprogs without -fomit-frame-pointer. The strace output is attached.
I forgot to add: reiserfsck alone on the command line does not segfault.
Got the same problem here, reiserfsck segfaults when checking /dev/sda5 (/usr) snippet from output: ------------[ cut here ]------------ kernel BUG at mm/filemap.c:1930! invalid operand: 0000 [#10] PREEMPT CPU: 0 EIP: 0060:[<c013b669>] Not tainted VLI EFLAGS: 00010282 EIP is at generic_file_aio_write_nolock+0xe9/0x100 eax: 00010286 ebx: 00010000 ecx: de230286 edx: de220000 esi: 00000000 edi: de221f6c ebp: de221e84 esp: de221e40 ds: 007b es: 007b ss: 0068 Process fsck.reiserfs (pid: 2400, threadinfo=de220000 task=df6452e0) Stack: dfd00000 00000000 00000000 c0430c80 00000012 dfcff340 dfcff3d0 df896a40 de221e84 df896a40 00010000 00000000 c013b7e2 de221e84 de221f6c 00000001 df896a60 00000000 00000000 00000000 00000001 ffffffff df896a40 df34dba8 Call Trace: [<c013b7e2>] generic_file_write_nolock+0xa2/0xc0 [<c021f100>] write_chan+0x180/0x260 [<c011df40>] autoremove_wake_function+0x0/0x50 [<c011c6b0>] default_wake_function+0x0/0x30 [<c011c6b0>] default_wake_function+0x0/0x30 [<c011be20>] scheduler_tick+0x210/0x4a0 [<c0219224>] tty_write+0x224/0x350 [<c015e137>] blkdev_file_write+0x37/0x40 [<c015534e>] vfs_write+0xbe/0x130 [<c0155472>] sys_write+0x42/0x70 [<c031cafb>] syscall_call+0x7/0xb Code: f2 90 8b 44 24 40 89 7c 24 04 c7 44 24 08 01 00 00 00 89 2c 24 89 44 24 0c e8 74 f4 ff ff 83 7d 10 ff 89 c7 75 cd e9 6f ff ff ff <0f> 0b 8a 07 ba de 32 c0 e9 53 ff ff ff 8d 76 00 8d bc 27 00 00 I also remerged reiserfsprogs, no luck, but after ^D sytem comes up normal.... root on dev/hda5 is mounted fine: Aug 14 16:39:32 bull found reiserfs format "3.6" with standard journal Aug 14 16:39:32 bull Reiserfs journal params: device hda5, size 8192, journal first block 18, max trans len 1024, max batch 900, max commit age 30, max trans age 30 Aug 14 16:39:32 bull reiserfs: checking transaction log (hda5) for (hda5) Aug 14 16:39:32 bull Using r5 hash to sort names Aug 14 16:39:32 bull VFS: Mounted root (reiserfs filesystem) readonly.
OK. Please UNpatch these diffs against your kernel tree: http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test3/2.6.0-test3-mm2/broken-out/reiserfs-bogus-kunmap-removal.patch http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test3/2.6.0-test3-mm2/broken-out/reiserfs-xattr-fix.patch http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test3/2.6.0-test3-mm2/broken-out/probe-udf-after-reiserfs.patch I assume these would fix the problem, if they do please say so, and I'll send Andrew the bugs you've been getting...

Hmm, looks like that won't work as they layer on top of the previous patch sadly. Try de-patching every aio-* patch in http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test3/2.6.0-test3-mm2/broken-out/ in order, 01, 02, etc...

Sorry, silly me: I forgot you need to remove them in reverse order too. http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test3/2.6.0-test3-mm2/announce.txt lists the patches and the order, you need to start unpatching from the bottom of the file towards the top, you can stop at aio-01-retry.patch, there doesn't seem to be anything else AIO related after that.
DONE... now Kernel comes up fine.. I used a fresh emerge of mm-sources and only unpatched that aio-stuff you've suggested, the (un)patches for reiser are still in.
Thanks a lot for your testing and contribution to kernel development ;-) I'll send a mail off to Andrew Morton and see if he can say anything on this...
It was a bogus "BUG_ON" command in mm/filemap.c. Removing line 1930 should fix your problems.
... of mm/filemap.c
In portage. If you sync and remerge it should work. Marking as fixed.
Thanks for your help. The kernel compiles fine.

Works now. Thanks a lot !
