It hangs due to the usage of synchronize_irq within the interrupt
handler. It does not look like it was intended usage for this. Removing
this code it does not lock up anymore. But it is not working either.
Looking through the code it uses the same configuration values for BNC
and AUI which de2104x uses for AUI.

Changes done so far are appended as patch.
