Right, this is the ECC happening. I asked about the dmesg because of
the "error reading F3x180" but you have a K8 machine so no extended PCI
config space there. And the error message is wrong there, I will move
that F3x180 read behind a family check since it makes no sense to access
that on K8.

Thanks.
