>Organization:
n/a
>Environment:
Any PCMCIA card containing a standard sio interface, e.g.
modem cards.
>Description:
If the irq line that is defined in /etc/pccard.conf
for that card is already in use by some other device,
the sio driver will nevertheless attach the card to
that irq line - or so it seems at last.
>How-To-Repeat:
define irq 8 (that's rtc) in /etc/pccard.conf for
some modem card, restart pccardd and plug the card
in.
This will be accepted, and the card will work (somehow
at least...)
>Fix:
In sys/isa/sio.c, right at the end of sioattach(),
the irq line is given to bus_alloc_resource(). If
this succeeds, BUS_SETUP_INTR() is called. If it does
not succeed, nothing is done and sioattach returns
successfully. This should be changed.
