[USR-TC] Hiper Arc reboots caused by DSP?

Hello everyone, Curious if anyone has seen or is familar with this problem: It appears that by inserting specific DSP's into a chassis (DSP's that we believe are messed up at this point) it causes 1 of our hiperarcs to reboot. It goes into a crash dump sequence. This chassis is doubled up but only 1 of the arc's reboots. If we replace the DSP's the arc comes up and works fine. This tidbit was of course figured out after replacing arc and chassis. Anyone see anything like this before and have any other points of interest? Todd
