Code:
apm0 at bios0: Power Management spec V1.2 (slowidle)
apm0: AC on, battery charge unknown
acpi at bios0 function 0x0 not configured
When your hardware has both APM and ACPI available, the default kernel will use APM. ACPI can cause problems .... and it can fix problems -- entirely unrelated to power management. So using ACPI may fix your PCI problem. In order to use ACPI, you must run a kernel with APM disabled.

To create such a kernel, use config(8). For example:
# config -o /bsd.acpi -e /bsd
UKC> disable apm
UKC> quit
Then later, at the boot> prompt, just type the test kernel name:

boot> bsd.acpi

This might also be the source of your problem:
Code:
pcibios0: PCI Exclusive IRQs: 5 10 11
pcibios0: no compatible PCI ICU found
pcibios0: Warning, unable to fix up PCI interrupt routing
I would start with an APM-disabled kernel, and see if that fixes it. If not, I'd want to see if the dmesg has the same PCI and IRQ errors.

If it does, I'd hunt down the devices that demand exclusive IRQs, and kill them.
