Martin Franc reported that the pciehp driver was not enabling bus master capability on his hot-plugged card. pciehprm_enable_card() was updating the PCI command register only if _HPP indicated a value for SERR or PERR that was different from the current setting. I don't have hardware that reproduces this problem, but Martin reports that this patch fixes the problem for him.
