That certainly can be a problem, especially if one tries to use more 
than 1 X100P card.
Have you tried enabling one port at a time?
If you are using multiple X100P cards though . . .
Motherboards vary all over the place, so there isn't a pat answer.
The TDM400 card is even worse. MB's that advertise PCI 2.2 don't always 
work, and anything less , forget it.
One reason several in the US have moved to the Cisco 3810 as a six port 
outboard ATA using SIP
Cheaper, if you buy them right, and many fewer hardware issues.
