Hi,
I installed OpenBSD 3.4 onto a notebook and I'm having CardBus/PCMCIA
problems.   Specifically, although the Texas Instruments 1225 interface
is being recognized, I can't seem to get the system to recognize that
any cards are present in the slots (i.e.  they don't even register as
unknown).  I've tried a handful different cards with the same result.
Note that the hardware is good as the slots and the cards are detected
under Windows 2000.  Windows 2000 lists a series of memory addresses for
each card, none of which line up as the OpenBSD socket base address.  I did
get one odd message during boot "cardbusmatch: bus name differs pcmcia <=>
cardbus" but I've traced through the code and I think this is normal (it
seems to pass the same interface to both cardbus and pcmcia routines).
Note that I am running a stock kernel with the exception of adding the
debug lines and a change to the AUE USB ethernet code (there is an error
in one of the flags which causes a kernel crash).

Is there some trick to get it working?  Any suggestions on what code to
look at if it's broken?

Thanks in advance,
Rob Ginn

Here is the dmesg (note that I've added DEBUG messages and turned on
extra debugging for pccbb.c, cardbus.c and cardslot.c code):
