Mesa Error Help

Converted this machine about 4 or 5 months ago. It has been running great till yesterday.
It started throwing these errors all at once and it happens at random times. It requires a complete shut down and reboot to get back up and running.

Where do I start PC, 5i25, or 7i77?

Thanks,
Kent

My guess would be that the system has lost connection the the 5I25 because
the laundry list of pretty much all possible SSerial errors probably means
that the host PC is reading an undriven bus so all 1's (0xFFFFFFFF)

This could be for a number of reasons.

1. Card not firmly in slot
2. Dirty PCI slot contacts
3. 3.3V PC power supply low (which will reset the 5I25)
4. Bad/failing 5I25 card
5. Bad/failing PCI slot on PC
