Problem Description:
The Oops message was outout from kernel with xfs filesystem on dm_crypt
With 2.6.15 and 2.6.18 Oops was output.
With 2.6.17 the system do kernel panic end.
The constitution of filesystem
[Disk x 6]--[sata_nv]-------------+--Raid6--dm_crypt--XFS
[Disk x 6]--[sii3132(sata_si124)]-+
I copied the files (all size=~1T) to the XFS file system by "rsync" or "cp".
Once in about 10 hours, this problem occurs it.
The Oops message is following
