reliable "panic: isa_dmastart: bad bounce buffer"

Tue Apr 12 20:14:58 PDT 2005

Hello!

Whenever I try to mount a floppy disk:

	 mount -t msdosfs /dev/fd0 /mnt

I get:

	panic: isa_dmastart: bad bounce buffer

The OS is FreeBSD-5.4-STABLE from last night, amd64. dmesg attached.

DR-DOS boots perfectly fine from this floppy...

Any ideas? Thanks!
