What USB controller are you using? Looks like you're not only
losing an IAA IRQ -- seen AFAIK exclusively on VIA -- but the
watchdog timer isn't recovering from that.
A better fix would be finding out why the watchdog isn't doing
its job in that case. That'd likely fix some other issue, and
wouldn't have the drawback of a memory leak.
