If the system is crashing then you can get null data in recently
changed files, this is in the XFS FAQ.

There is a completely unrelated problem in flushing IDE drives before
suspend/shutdown that can give the same symptoms, even on a clean
shutdown.  Andre Hendrick has been trying to get patches into the
kernel to ensure that IDE drives are flushed on shutdown.

People have reported similar symptoms with several filesystems when the
init scripts fail to flush the IDE caches on shutdown.  hdparm -f on
each device might help.
