I don't have a patch ready, but I believe we localized the problem to
serport_ldisc_read().
wait_event_interruptible(serport->wait,
+test_bit(SERPORT_DEAD,&serport->flags));
It does interruptible wait, but does not expect signals. We tried
something like:
do {
wait_event_interruptible(serport->wait, test_bit(SERPORT_DEAD,&serport->flags));
} while (try_to_freeze());
...but that did not help IIRC.
