I've been running the latest i386 current snapshot on my Toshiba
Portege SS 3010 for almost a month, and I love this thing! But
there's one thing that's been bugging me.
Hot-insersion and removal of PC cards are not detected properly. A
state transition (insersion or removal) has to occur in *both* slots
in order to be detected.
For instance, assume I have a modem card inserted in slot 0 and
nothing in slot 1. When I remove the modem card, it goes unnoticed,
but when I put it in the other slot, first slot 0 removal is detected
(and comN device gets detached) then slot 1 insersion is detected (and
comN device gets reattached in case of the modem card).
If I remove the modem card from slot 1 again and slap it back into
slot 0, this time, insersion in slot 0 gets detected first (comM
device attached, where M = N + 1), then removal from slot 1 next (comN
This is sometimes annoying, especially when I'm using an Ethernet card
in one slot and want to insert a modem in the other slot for some
reason. Simply inserting the modem card doesn't make kernel detect
the card. I would also have to remove the Ethernet card in the other
slot but it would cause a kernel panic (When is if_delref() going to
be implemented, BTW?). I have no choice but reboot the system to use
I asked some FreeBSD people and they say they don't have the problem
even on the same model. I suspect it has something to do with the way
pcic interrupt is set up under NetBSD, but I know nothing about
Excerpt from dmesg:

> pcic0: controller 0 (Intel 82365SL Revision 1) has sockets A and B
I appreciate any insight.
