It could be a grounding problem. I've seen the a shutdown triggered on an un-grounded ROACH-1 when the chassis is touched due to ESD discharge.
Unfortunately, "user shutdown" is probably about the best logging you're going to get. This implies that the Actel Fusion received a shutdown request. I believe this can only come from a software process on the PPC or the hardware button on the front panel.
