I already had
hw.pcic.ignore_function_1=1
in "/boot/loader.conf" in order to get my PCI<->PCMCIA adaptor (with a "wi"
device) to work. (This was advice from Warner Losh.) But I didn't have
"hw.pcic.intr_path" or "hw.pcic.irq" set, because they didn't seem to be
needed before.

The good news:
- when I added those two lines (to "/boot/loader.conf"), I was able to also add
snd_maestro3_load="YES"
to load the PCM device:
pcm0: <ESS Technology Allegro-1> port 0x1000-0x10ff irq 5 at device 13.0
on pci0
without the kernel hanging during booting.
The bad news:
- when I added these two lines (to "/boot/loader.conf"), my "wi" (Orinoco
wireless LAN) device no longer initializes properly:
wi0 at port 0x240-0x27f irq 13 slot 0 on pccard0
pcic0: Hardware does not support irq 13.
wi0: bus_setup_intr() failed! (22)
device_probe_and_attach: wi0 attach returned 22
beforehand, the "wi" device would initialize (correctly) as follows:
wi0 at port 0x240-0x27f irq 3 slot 0 on pccard0
This "pcic" stuff is a black art to me. Any idea what I can do (e.g., in
"/boot/loader.conf") so that (i) my "wi" device initializes correctly, and
(ii) I can load the ESS Allegro audio device? (I've cc'd Warner on this
msg, although he's probably sick of answering questions about "pcic" :-)
Ross.
ps. Another (possibly) dumb question: Assuming I can get the PCM device
loaded correctly (without messing up my "wi"), how do I then create the
/dev/pcm device? I.e., what arguments do I give to "mknod"? ("pcm" is not
mentioned at all in "/dev/MAKEDEV")
