I analyzed the driver again and found another issue: I once decided to
request the IRQ to register the ISR (although it isn't used), because I
had the problem that some adapters raised interrupts, even when not
commanded to do so. When changing this, I obviously forgot to free the
IRQ again when unloading. This is probably the reason for your freeze.
Please try the snapshot with revision 1817.
