I've made b43 and wl dumps almost identical on Juan's HP machine. I
still get DMA errors.
Does anyone still have patch to enable dumping PCI operations?

The attached patch will log the reads and writes to the PCI config registers. Is
it the one you wanted?

If we assume that:
1) Problem with b43 and DMA is pci config related
2) Config writes done by wl can be noted by reading
Does it make sense to dump PCI config with "lspci -x" or "-xxx" for
cold boot vs. loaded&unloaded wl?

I don't know if it will show anything, but it is an easy test.
