Hi,

I've been trying to get a wireless card runnning using -current (checked 
out august 6th) on my Blue & White G3.

The wireless card is a Farallon SkyLine inserted into a PCMCIA PCI 
adapter. The cardbus bridge (a TI PCI1410) get configured properly. 
Sadly, I get a panic when the wi device is being configured. ddb trace & 
ps, dmesg and objdump of if_wi.o below.

If I disable wi, everything is fine.

Cheers, Otto
BTW: panic msg and ddb output hand typed.
