Get the cards on their own interrupts - use the BIOS, turn off unneeded 
onboard devices etc.

If you still have problems and the FXO modules are marked "Rev C" on the 
non pin side, talk to Digium support.

I had ongoing problems with FXO modules stopping responding and 
requiring reboots to restore. Regdumps of the offending module show "ff" 
loaded in almost all registers.

After contacting Digium, I was told this was a hardware issue and after 
having them replaced with modules marked "X100B RevB", I have so far had 
no problems.
