Compact Flash panic integer divide fault

Hi,

Since some time FreeBSD-current panics with a compact flash disk
in a pccard adapter. The kernel panics with "integer divide fault"
as soon as the card is encountered.

I first saw the "integer divide fault" with a kernel build on
November 6th.
With a newer kerner (Nov 10th) the panic changed into
 "panic: page fault".
Now, the "panic: integer divide fault" is back again.

Appended is a log from a kernel build last Friday (after a cvsup).

The system is a Toshiba Portege 7220, the compact flash disk is a
SanDisk. I tried it with two different cards (a 128 and a 32 Mb).
Both cards work fine with an older system (build in Sept 2003).
