Check that last item you've listed - the file system. The problems sound 
amazingly familiar to what I was seeing when running XFS, LVM, and a 
couple of 250GB disks on my video partition. There was another factor in 
there that escapes me at the moment but changing that partition to ext3 
completely resolved the instability for me.
