Hi,
have the same problem, however ...
> void pcmcia_parse_events(struct pcmcia_socket *s, u_int events)
> {
> + if (unlikely(&s->init_done == 0))
... this cannot work because of the "&". Of course, the _address_ of
s->init_done is always non-zero. Also, the problems are related to yenta_socket.c
The interrupt occurs during irq-probing in yenta-socket.c, so the problem should
be fixed _inside_ yenta-socket.c and not touch any other part of the pcmcia stuff.
I.e. add that "init_done" flag to "struct yenta_socket"; not to struct socket.
It should work then, just trying now ...
Greetings
Claus
P.s.:
