Well I just want to count my self in. - I have had quite a few of these
both on XFS and EXT3. I tried a lot of different 2.6.x kernels without
luck. (See other mails here on LKML from me and Jakob Oestergaard et al.) 

It seems something is very broken in VFS(?) on 2.6 (atleast after 2.6.5,
which was the last kernel I didn't see this on, but had other errors that
forced me away from it).

Sadly it looks to me as if either noone cares (enough) about this, or noone
is capable of fixing it (myself included). :( 

- 2.4.28 fixed it for me. - Just have to live with the poor performance.

In the last week I got the following Oops five times on two machines,
when they are under very heavy load  (mailserver based on Debian sarge
with postfix 2.1.4) when the load is >4 for some hours.

I run a 2.6.10 kernel (with aacraid 1.1.5 2372 driver from Adaptec,
everything else vanilla) on Dual Xeon machines. The kernel has ext3fs
and XFS compiled in but currently all filesystems are ext3.

In the logs I don't see anything, because the machines freeze with the
above message (I retyped the messages from the screen, so there may be
some typos, if necessary I have a screenshot here to correct some

What can I do to fix this problem?  Using google I didn't find a hint
for further search, but my kernel knowledge is very limited :-|
