That may be Pavel's position, but USB-wise we absolutely consider
it a bug if Linux misbehaves in the face of routine actions like
unplugging a device during suspend (or plugging in a new one).
Regardless of "noresume" etc.
I'd say that's true for all hotpluggable busses, in fact, but I
rarely submit patches for non-USB ones like PCMCIA or CardBus.
