: 
: 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.

dc isn't going to run on OLDCARD :-).  I have used rl and ep based
cards in my 8100.
