Hi,
Thanks for the quick reply! I have compiled a new kernel (just uniprocessor
for
the moment) with the suggested options and attached the dmesg output. It looks
like the kernel isn't able to figure out the PCI-X and PCI-64 buses on the AMD
8131 at all ("failed to derive bus number"). IIRC there should be a second
root PCI bus there as well. It also seems weird that all the interrupts are
mapping to isa0. Is my motherboard firmware simply broken? Is there anything
I can do if it is?
BTW, if I enable MPACPI in the kernel options, should I also turn off MPBIOS?
Similarly, are MPACPI_SCANPCI and MPBIOS_SCANPCI mutually exclusive?
Hmm.. obviously it does need some extra tweaking somewhere (since Windows
does get it right), but I'm not sure where that is. It seems that the
BIOS possibly doesn't initialize some PCI bridge registers. Also,
MP*_SCANPCI are designed to find extra root buses, and those options
do normally work.
Hmm, I suspect he is a victim of the bug I fixed in November last year in
sys/arch/x86/x86/mpacpi.c, where the bus number on the wrong node is tested.
Unfortunately, I missed to request a pullup of this change to the netbsd-2
branch :-(. And I'll not be able to do this in a short timeframe either,
as this seems to require a patch. Maybe, you can?
Otherwise, maybe Chris can test with a (more) current kernel?
Ciao,
Wolfgang
