I manage to get a PCMCIA network card with another chipset.  It uses
the dc(4) driver.  This time, with rev 1.49 of cardbus.c, the system
panices whereas it works quite well with rev 1.48.  Having dc(4)
compiled in kernel or as a kld doesn't change anything.


Here is the end of dmesg (the box was booting), the panic message and
the backtrace (hand-written) :

I got a dump.  Please contact me off-list if you want it.

Here are the card info:

      device   = 'AN985 FastNIC CardBus 10/100 Fast Ethernet Adapter'

I hope this will help.
Best regards,


PS: Note there seems to be a whitespace typo on the following line,
just after the first comma, a space seems to be missing :
  dc0: requested interrupt 6-6,count = 1 not supported by cbb
