Well, that's as good a reason as can be expected under the circumstances. Some level triggered hardware interrupt signals will stick around until the conditition that triggered them has been taken care of. Simply unhooking the int2/int6 handler chain will not help, as the interrupt condition will persist and the system might just stall until it has been serviced. I remember wrestling with this kind of issue on the Concierto sound card driver

So this probably means that Roadshow won't be able to function completely under these circumstances either. But it might be possible to temporarily switch the networking interfaces offline while WHDLoad is doing its stuff.
