Look at http://oss.sgi.com/bugzilla/show_bug.cgi?id=840
Please provide your dmesg output regarding kernel oops message (maybe
there is similar issue in your case as I had)
It seems that in my case it was a problem of HBA configuration (using
LVM2 and caches) as Christoph Hellwig replied. After proper
configuration I had similar issues still, but last Friday I upgraded HBA
firmware because I've found that there was an issue with cache mode
report (software reported that write caches are disabled but they were
still enabled). I hope this will help in my case - for now I had no
crash. We'll see within next week (it occurs about once a week).

In your case without oops message it's really hard to tell what's wrong.

Best regards,
Tomasz Kruszona
