What kind of card? There is a known problem with busdma and some
interfaces including if_dc. (I have a Xircom that uses this driver, but
I have seen reports of the problem on several others.)
I have a work-around from scottl for if_dc, and another from Takashi
Naguchi with a one-line change in busdma_machdep.c that fixed his
problem. (Note: These are hacks and not real fixes.) I will attach them.
I can only vouch that the if_dc.c patch prevents the hang. I have not tried
the second nor have I tried using the Ethernet portion of the Xircom. I only
use it for the modem.
