I just purchased a nice outboard USB 2.0 drive and, well, I'd like to
leave that drive plugged in while I reboot my machine. However, when I
do so, BTX panics and spews all over the place:
(I have to type this in, as I can't get a good screendump except by
photographing the video screen with my cellphone camera):

> BTX loader 1.00  BTX version is 1.01
> Consoles; internal video/keyboard
> BIOS drive C: is disk0
> BIOS drive D: is disk1
> int=0000000d   err=00000000  rgl=00030002 eip=0000461e
> ...more lines
> BTX halted

I see this PR:
but I'm not quite sure if it's the same issue or not.

Any ideas, other than rushing to unplug the device if the machine reboots?
