: So, the problem is that we turn on the memory BARs by default. Note
: that the BAR has a base address of 0, so I wonder if it starts
: "answering" to mem access to low memory. Note it has a range of 27
: bits, or 128 MB. We could probably just move the check for a base of 0
: up above the pci_enable_io_modes code to do that. Warner, what do you
: think?
Sounds reasonable to me on its surface. Wanna shoot me a patch?
