Thank you Peter, the above patch removed the "possible recursive
locking detected" message.
Now, I've got a new one (will this thread never end ?):
pktcdvd: writer pktcdvd0 mapped to hdc
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.
