Hi Steiner,

Sorry for not getting back to you right away; I've been doing a huge amount of
travel right during January.   Can you tell me something about the file system
workload on your machine?  What does it do?  NFS, rsync server, backups, ...?  
And do you know what it might be doing right before it crashed?   How easily
can you reproduce this?  I take it since you had to stop using 2.6.33-rcX you
could reproduce it easily?

If you are willing to try a 2.6.33-rcX kernel, I'd suggest seeing if "echo 0 >
/sys/fs/ext4/<dev>/max_writeback_mb_bump" makes the crashes go away.
