I am running XFS on a software raid 5. I am doing this with a PCI
controller with 4 SATA drives attached to it.

When I play my music over the network through Samba from the raid
volume my audio client will often loose the connection. This isn't
remediated until I restart the machine with the raid controller or
wait for an unknown amount of time. Either way, the problem still
persists.

Initially I though that this was Samba's fault, but I think it may be
xfs related due to what was in /var/log/messages:

It looks like you've edited this a bit too much, what came before this in the 
logs?

Are you running on 4k stacks, out of curiosity?
