Trying to mount a cdrom from my XP box using
        mount_smbfs //jason@desktop/cdrom /cdrom
Causes my machine to panic and die. Below is hopefully some info that
will help resolve the problem
Included as an attachment in plain text format the boot sequence showing
my hardware.  The motherboard itself is
An Asus CUV4X

I will keep the core file itself for a few days under the name
smbfs.smp-kernel.core (I seem to generate a boatload
Of core files, and even on a 40 gig drive I'm running outa space fast)
if anyone needs more info.
