Hi,

Is there any way that you could hook up a serial console to the machine
and record what the SCSI errors are?  Without any specific information,
it's hard to diagnose the problem.  That said, there is a known problem
with the raid controller driver for that machine that can cause lost
i/o, though that doesn't sound like something that is affecting you.
This particular bug will be fixed in 5.2.1.
