Subject: Kernel 2.6.19.2 New RAID 5 Bug (oops when writing Samba -> RAID5)
My .config is attached, please let me know if any other information is
needed and please CC (lkml) as I am not on the list, thanks!
Running Kernel 2.6.19.2 on a MD RAID5 volume. Copying files over Samba to
the RAID5 running XFS.
Any idea what happened here?
