The "machdep.." line wasn't there, but was commented out in
/boot/defaults/loader.conf (so I left that was it was).
Hmmm, I changed the "pcic" irq to 11, but still get:
pcic-pci0: ... irq 10 ...
pcic-pci1: ... irq 10 ...
pcic0: management irq 11
No go. I also commented out the USB device lines (uhci0 was also at irq 10)
in the kernel config file and what do I get ?
pccardd[45]: No card in database for "3COM"("3CCM156 B")
ep0: <3Com Etherlink III 3C589> at port 0x240-0x24f irq 10 slot 1 on pccard1
ep0: Ethernet address 00:10:4b:ed:e6:eb
ep0: supplying EUI64 00:10:4b:ff:fe:ed:e6:eb
<hang>
ctrl-alt-esc shows more lines than fit on the screen, but the path is:
(off the screen bits)
pccard_beep_select
BUS_SETUP_INTR
bus_generic_setup_intr
BUS_SETUP_INTR
bus_setup_intr
ep_isa_match_id
DEVICE_ATTACH
device_probe_and_attach
pccard_alloc_slot
pccard_event
spec_vnoperate
...
If that is freezing because there is no speaker device (I copied my
config from GENERIC which has no sound driver configured), then config
should not allow this sort of configuration bogon. I'm trying to
configure some sound devices with varying levels of success.
