still hanging.

This prevents the "not_implemented" messages from coming up but still
the systems hangs after the following messages which I didn't see
before:

bfe0: BUG! Timeout waiting for bit 00000002 of register 42c to clear.
bfe0: PHY Reset would not complete.
bfe0: BUG! Timeout waiting for bit 80000000 of register 428 to clear.
