Hi! tsutsui-san


I tested PCI_NETBSD_CONFIGURE by the following device further.

        esiop, ahc, rtk, tlp(PCI card)

esiop, ahc and rtk(use mem space) fail in the address error.
Only tlp worked.
# It seems that it will become an error if vr uses a memory space
# now.

Furthermore, when it was in the usual state, it checked that
those devices worked.


If this difference was investigated, one will have noticed
COMMAND_STATUS Register being different. It seems that it will
fail if both of "Parity error checking" and "System error (SERR)"
of COMMAND Register are specifically on.

I turn OFF "System error" (SERR) and took care to have not fail.


thanks.
