Um, Ted? This may not be strictly related, but it's possible to get a "Wild
interrupt?" on the IRQ of a bus mouse if you load a mouse driver under DOS,
then later warm-boot into Linux --- since DOS doesn't have a shutdown
procedure, if the mouse is activated (by the mouse driver) it can send a
spurious interrupt (generally from being moved at some point during the
reboot) which will be detected by Linux before the Linux busmouse driver hooks
the interrupt and reconfigures the mouse. I saw this quite often back when I
was constantly booting from DOS to Linux and back (then-unsupported software,
namely NOS).
