The problem you describe is becoming common in the 4.x versions of
FBSD.
I have seen these solutions voiced previously in this list.
1. Check the PC's bios, look for a toggle to disable plug-n-play
function.
2. Check that your PCI cards are not in the first or last PCI
expansion
slot on the motherboard.
3 add option PCI_ENABLE_IO_MODES
to your kernel source and recompile. See LINT
4. add device puc
option PUC_FASTINTR
to your kernel source and recompile. See LINT
5. Follow bug fix using this url
http://www.freebsd.org/cgi/query-pr.cgi?pr=40636
6. check /var/boot/dmesg.boot file to see if your pci cards are
found
as unknown. See FBSD FAQ for instructions on how to fix.
Try one of the above one at a time until your problem goes away.

Subject: Resolving IRQ conflicts with 4.8
Hi,
If this post is considered off-topic, forgive me. Perhaps someone
might be
willing to work with me off-list?
I have 3 PCI devices using IRQ 9!
The modem, nic and built-in sound card.
I've physically removed the modem, because it was being detected
before the
nic, and I had no ability to network.
In BIOS, I have PnP OS set to "No".
There is a setting to allow resources to be controlled manually, but
this
defaults to "Legacy ISA device".
Since I have no ISA devices, this won't work.
I noticed from output of dmesg, that it does some probing for PnP
devices:
Probing for PnP devices on ppbus0:
ppbus0: <Hewlett-Packard HP LaserJet 1100.1.0> PRINTER MLC,PCL,PJL
What, if anything can I do so that I can have my nic, modem, and
sound card
detected during boot?

Thanks,
Charles
