Created an attachment (id=284)

system message log during the problem.

OS: openSUSE 11.2

I first reported this issue in 2007 in Novell Bugzilla (oS 10.3). I thought it
was solved in the last oS release, but it is not so.

Old report: <https://bugzilla.novell.com/show_bug.cgi?id=345039>
Current report: <https://bugzilla.novell.com/show_bug.cgi?id=567912>

You can track the full details in the Bugzilla there. I report it here because
I hope you will be more interested in solving this long standing issue.



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

I had created 4 XFS, LUK encrypted, 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.

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

I will attach message log showing kernel oops.

Please ask any more information you need.
