Hiya, (we are running a custom board very similar to pq2fads)
I am having some issues with the resource allocation of the host bus in
2.6.17.3 where by on startup the kernel complains below the lines:
[ 8.824450] PCI: Cannot allocate resource region 0 of device
0000:00:00.0
[ 8.843507] PCI: Cannot allocate resource region 1 of device
0000:00:00.0
We are using the same memory map (did'nt) override the pq2fads code
I also output lspci. What should it be doing here? How do I correct
this?
Cheers
Tony
