I've been running into a kernel panic pretty consistently when using
data=journal. This occurs during heavy IO, and is highly reproducible
(only takes about 5 minutes of IO to cause it). The applications being
used are MySQL, Postfix, and a mail filtering application which operates
on postfix queue files using mmaped IO.
Shortly before the crash, the following messages are logged:
Mar 2 14:15:30 test5 kernel: Unexpected dirty buffer encountered at
do_get_write_access:618 (03:05 blocknr 3688784)
Mar 2 14:16:04 test5 kernel: Unexpected dirty buffer encountered at

Mar 2 14:18:38 test5 kernel: Unexpected dirty buffer encountered at
do_get_write_access:618 (03:05 blocknr 3692808)
I've duplicated it in 2.4.22 and 2.4.25. Here's the crash from 2.4.25:

Any help would be greatly appreciated! Please let me know if any more
info is needed.
