I just upgraded from linux-2.4.21 + vserser 0.17 to 2.4.30rc3 + vserver
1.2.10. The box has been running stable with 2.4.21 + vserver 0.17/0.16 for
a few years (uptime before reboot was nearly 400 days.)

The boot went fine, but after few hours I got 
Message from syslogd@box at Sun Mar 27 22:07:00 2005 ...
turing kernel: journal commit I/O error

and dmesg is filled with 
--8<-----------------------------------------------------------------------
EXT3-fs error (device md(9,3)) in start_transaction: Journal has aborted
EXT3-fs error (device md(9,3)) in start_transaction: Journal has aborted
EXT3-fs error (device md(9,3)) in start_transaction: Journal has aborted
EXT3-fs error (device md(9,3)) in start_transaction: Journal has aborted
--8<-----------------------------------------------------------------------

This is roofs, on top software raid1 and two ide disks. mdstat claims it's
healthy:

--8<-----------------------------------------------------------------------
md3 : active raid1 hdc3[1] hda3[0]
      37955648 blocks [2/2] [UU]
--8<-----------------------------------------------------------------------

While dmesg has filled up and /var/log/messages is read-only - I can't see
all the kernel messages - there appears to be no IO errors from the
underlying devices (md, ide). smartctl -a does not report errors for hda nor
hdc.

During reboot, fsck was run for md3, and it was clean. Now I get

--8<-----------------------------------------------------------------------
Block bitmap differences:  -(7800660--7801060) -(7801934--7802030) -(7802370--7802602) -(7802604--7802613) -(7802681--7802700) -(7802715--7802716) -(7802726--7802732) -(7802744--7802750)-(7802914--7802927) -(7802934--7802937) -(7802946--7802964)  -(7803392--7803417) -(7805060--7808825) -(7808976--7809608) 
Fix? no

Inode bitmap differences:  -3899400
Fix? no
--8<-----------------------------------------------------------------------

No errors from the badblocks part of the fsck, though.

Running fsck triggers the "journal commit I/O error" messages again, and
still no IO errors from either md or ide.

This _could_ have something to do with the vserver patch but it doesn't
appear so. Also, it doesn't immediately look like hardware problem. 

Any ideas?
