Have a look at trap_64 in cheetah_deferred_handler. There is a pci_poke_faulted variable that is used to flag these errors and to skip the instruction. From a quick look at the driver, this shouldn't be happening. The PCI space should be configured first. I would enable ql_dbg output to see more of what is going on. Perhaps one of the messages above indicate an issue and the return value isn't being validated correctly? Or perhaps the error path assumes it is safe to access the PCI bus when it's not safe?
