Hi,

I have an easily reproducable panic when using atapicam.  Vague trace
follows:

panic was caused by this:
KASSERT(bp->b_flags & B_PHYS, ("vmapbuf"));

trace:

vmapbuf
cam_periph
xptioctl
spec_ioctl
spec_vnoperate
vn_ioctl
ioctl
syscall

Let me know if you need any further information, this panic is easily
reproducable for me(cdrecord --scanbus is enough).

Regards,

Stuart
