Hi,
I'm working with the Freescale evaluation board MPC8641DHPCN and the
VIRTEX5 evaluation board ML555 connected with the PCI-Express. When I
try to read some register I have this problem:
Machine check in kernel mode.
Caused by (from SRR1=149030): Transfer error ack signal
Oops: Machine check, sig: 7 [#1]
