SubjectRe: usb dc2xx quirk
If this makes it go away, then by all means apply this patch;
though I don't quite see what the failure mode would be.

The proximate cause of that Oops looked to be in one of the
UHCI drivers, but of course it's also possible that it was
triggered by driver misbehavior.

Have we identified anything that actually does anything with
code labeled __dev{in,ex}it (or data), beyond putting it into
a different section? If so, what's it doing?
I just tried plug/unplug of a dc-240, albeit on a kernel
with HOTPLUG defined (and using OHCI) and it worked without
any Oops.
