With the new flag the semantics change, as soon a panic write happened, the flag will stay and *all* future operates will take the polling/pio path.
IMHO this is fine since the kernel cannot recover from an oops. But just to make sure we all get this. :-) An alternative would be to block all further non-panic writes.
