The following reply was made to PR i386/74601; it has been noted by GNATS. From: "M. Warner Losh" <imp@freebsd.org> To: freebsd-gnats-submit@freebsd.org, oberman@es.net Cc: Subject: Re: i386/74601: Cardbus fails after busdma_machdep.c update Date: Mon, 06 Dec 2004 15:56:23 -0700 Can you add debugging code to see where in the process the system freezes up? The dc driver isn't doing any DMA in its attach routine that I can easily identify. It should print a NIC address in boot verbose. It would be useful to know if it is getting there. It would also be useful to know if it makes it out of the dc_attach() routine at all. I believe that this dc card also has a miibus attachment to it as well, but I haven't tracked down to see if there's DMA there or not. I suspect not because MII interface control tends to be bit-bangging fun/pain.
