System: NetBSD zorkmid.mit.edu 1.5Z NetBSD 1.5Z (ZORKMID-$Revision: 1.12 $) #110: Sun Dec 16 22:49:07 EST 2001 jhawk@zorkmid.mit.edu:/usr/local/netbsd-current/src/sys/arch/i386/compile/ZORKMID i386
>Description:
Try to use a 3Com Megahertz, 3CXM756/3CCM756 (manufacturer 0x0101,
product 0x003f) pcmcia card on my Sony VAIO Z505HE. It seems to work
fine when cardbus is disabled and it is attached on pcmcia0 at pcic0,
but it fails when attached on cardslot0 at cbb0.
The specific failure appears to be one of interrupts. Despite the fact
that an interrupt handler appears to be registered, no interrupts
are generated when the card is plugged in (e.g. a breakpoint on Xintr9
never triggers). Interrupts work fine with wi0 attached in the same way.
>How-To-Repeat:
Here's dmesg output with CBB_DEBUG, PCIBIOS interrupt debugging,
and perhaps some other kinds of debugging, too.

Which all looks totally normal.
pccbb_intr_establish() and it's companion pccbb_intr_route() both
appear to be really straightforward functions without a lot of stuff
to go wrong.
>Fix:
Well, using the pcmcia attachment works just fine. I dunno beyond that.
It was suggested I try futzing with the PCIBIOS fixup options.
INTR fixups are required for my cbb to even attach, and beyond
that, the other combinations appear to have no practical effect.
I'm really at a loss to how to debug this. I'd appreciate some
assistance...
