I am hitting what seems to be a bug in one of my Linux storage layers, this is
my system:

The three hard drives in raid are Western Digital RE4 WDC WD1003FBYX with write
cache enabled (yes i know i have write barries disabled in fstab).
I use this raid to backup my machine with rsnapshot than uses internally rsync,
it seems that, given sufficient pressure, i can almost always crash xfs
filesystem and my machine with it, i have attached what it's logged in
/var/log/messages.

Miguel Angel.
