messages log at the time it crashed.

Under some circunstances, an XFS filesystem may lock and crash the entire system

I had created 4 XFS, LUK encripted, filesystems, of DVD size, for backup purposes, on which I had copied several files, and was running par2 an all four of them. Suddenly, after perhaps 20 minutes, cpu usage stopped, the processes stuck and were unkillable, several partition were not umountable (all that were XFS, or the one that hold loop-mounted small xfs, encripted, filesystems). Processes showed in "top" as waiting - sorry, the screen capture has been lost in the process.

System could not be rebooted, I had to powercycle it.

I will attach message log showing kernel oops.

Upstream SGI says it is caused by a DM lockup, not XFS code.

Comment 4 Carlos Robinson 2010-01-15 20:45:20 UTC 
Mounting nobarrier avoids the issue in 11.2 - per the suggestion in the SGI bugzilla. It does not work for 11.0
Comment 5 Nikanth Karthikesan 2010-04-08 10:44:54 UTC 
This should be fixed now. Please verify.

Yes, indeed.
