My apologies if this has already been received by the list, but there was some
problem with my subscription.
I found some information after attempting to post this however. It basically
said that the behavious below was by design as freebsd supports irq sharing.
Also, after closer analysis of dmesg, I think the pcm device may be on irq 3.
Am I correct? Will specifying a different irq in the kernel configuration
force it to a different irq (hopefully freeing it up for use by the modem)?

Subject: pccardd forces irq 9 on pcmcia modem

Hello,
I'm having trouble with a pcmcia modem. It is actually detected and set up as
a "generic serial" but it runs very slowly. I should be able to get about
3.4k/s but can only get about 1k/s. I had the same trouble with Linux but was
able to fix it; I found that the irq was being set to 0 and setting it to 3
made everything run perfectly. Under FreeBSD, I tried setting up
/etc/pccard.conf as follows but it still forces it to irq 9:
irq 3
card "HONDA ELECTRON CO.,LTD" "AH-H401C"
config 0x9 "sio" 3
As you can see from the output of dmesg below, there is no other device on
irq 3. I also have another (lesser) problem; no pccardd entries appear in
/var/log/messages. If I run pccardd -d, they all show up fine on the
console. I tried uncommenting the "*.* /var/log/all.log" line in
/etc/syslog.conf, but they don't show up there either.
The output of pccardc dumpcis is as follows:
