I had a similar issue thatIi mitigated by installing a different network
card. I seem to recall the net chip was in close proximity to the perc
controller power access. When the system was loaded up on a big network
transfer that was doing heavy disk access, the lockup was frequent, but
a certainty. By disabling the onboard NIC and using a pci slot NIC the
problem went away. I suspect it was a power distribution issue but did
not chase it down.

I'm not a fan of the PERC hardware. It has always seemed a bit odd.
