Hmm... I have the same problem. But in addition to this one, when I have
cardbus enabled it no PCMCIA cards get detected at all.. I was waiting until
I figured this one out before I moved on to the cant get MAC address error.

Subject: my wavelans hate my toshiba laptop...

        I am the happy recipient of some wavelan silver wireless lan
cards.  The unfortunate thing is that they hate my Toshiba Tecra 700CT
laptop.  The wavelans work fine in my PPro/200 machine via a
ISA->PCMCIA bridge card (one that comes with the WebGear cards FWIW)
but in the laptop the driver complains that it cannot get the MAC
address of the card like this:

Apr  2 19:24:09 rover /netbsd: wi0 at pcmcia0 function 0 port 0x380-0x3bf:
could not get mac address, attach failed

I did some digging in the if_wi.c and found that by putting some
delays around the register writes in wi_read_record I can get a mac
address back after a couple of goes which makes me wonder if there is
some odd timing problem with my laptop.  Do I hack the driver to put
delays around all the register reads/writes?  Any one got a better

BTW I have tried loading up the guff on my NT machine to try and
re-flash the cards but NT now does a BSOD soon after boot....sigh.
