This message comes from the kernel, from reading cpu port 61H.
It can have different meanings for different motherboards
and vendors, and is rarely adequately documented. Interesting
discussion here:

For us this error turned out to be the interaction of a pair
of PCI cards. We regressed a prom on the card, and the problem
vanished. Basically, the kernel messages won't tell you much.
Assuming the board's OK, it's probably a board - card interaction.
Good luck
