Package: kernel-image-2.6.10-1-686-smp
Version: 2.6.10-4
Severity: critical

2 months ago I bought 4 new hard drives, which I configured as follows:

-----------------------------------------------------------------
|  Linux  |  Swap  |                  RAIDSET-1 disk 1          |
-----------------------------------------------------------------
| RAIDSET-0 disk 1 |                  RAIDSET-1 disk 2          |
-----------------------------------------------------------------
| RAIDSET-0 disk 2 |                  RAIDSET-1 disk 3          |
-----------------------------------------------------------------
| RAIDSET-0 disk 3 |                  RAIDSET-1 disk 4          |
-----------------------------------------------------------------

RAIDSET-0 is 20G, RAIDSET-1 is 709G.

On top of both raid devices I use the device mapper to encrypt those
disks, so data travels to the disk through the following layers:

  vfs -> ext3 -> device mapper -> raid -> physical disks

Since the beginning I have been having problems with heavy disk usage
on RAIDSET-1. It seems that under normal circumstances the system is
stable, but under heavy load the following error occurs:

Feb 12 06:27:25 einstein kernel: EXT3-fs error (device dm-2): ext3_readdir: bad entry in directory #84509561: rec_len %% 4 != 0 - offset=0, inode=1629516644, rec_len=29795, name_len=117
Feb 12 06:27:25 einstein kernel: Aborting journal on device dm-2.
Feb 12 06:27:25 einstein kernel: ext3_abort called.
Feb 12 06:27:25 einstein kernel: EXT3-fs abort (device dm-2): ext3_journal_start: Detected aborted journal
Feb 12 06:27:25 einstein kernel: Remounting filesystem read-only

As I do some spam-learning and backups at night, requiring some heavy
disk use, this happens just about every day. Running fsck after the
error is useless, as it finds no errors at all. So there is little
else to do then remount and hope for the best for another day.

My system is a dual Pentium II 400MHz with 384MB memory. All four
disks are Hitachi/IBM Deskstar 250G. The problem occurs with every
2.6 kernel I have tried so far, starting from 2.6.7.

Typical thing is that it only seems to occur on -smp kernels. I've
been running some UP-kernels as well and (although slower) they do
not thrash the ext3 journal. Could this be an SMP race?

More system information can be found in the attached kern.log.

Regards,
Jeroen
