Going at it today.
One issue seems to be disabling interrupts by writing 0x0 to
CB_SOCKET_MASK in yenta_probe. I don't know enough about driver
development to know why that blows up, but the same thing is done
(with the same comment) in the 2.4 series' initialization (yenta_open)
as well. Preventing those via #ifdef results in the driver lasting
longer, but not much so - attached are the raw oops and same run
through ksym. Also, below is the debug output from yenta_socket.c up
to and including the first line in the oops file above (not really
part, but it's an anchor). Now we're really getting out of my depth.
