i have a pci cardbus adapter that i use in conjunction with my
orinoco wavelan card. unfortunately, my BIOS doesn't assign the
card an interrupt correctly. freebsd has some clever hacks to
overcome this and the card does indeed get an interrupt assigned to
it. i made a kernel with all of the pcibios code and it didn't help
any. i also tried another kernel with PCI_INTR_FIXUP_FORCE enabled,
but that didn't produce any results. so i have a couple of
questions here.
1) some of the pcibios interrupt message don't make into the dmesg.
anyway to fix this?
2) can someone point me to a good source of information on how
bioses map interrupts? i'd really like to get a solid understanding
of what is going on before i start trying to modify pcibios to use
the hacks from freebsd.
3) is there anyone who is good at this stuff that has any
suggestions?
anyway. the dmesg output is below.
thanks,
- jolan
p.s. the card doesn't get an interrupt mapped under openbsd either.
