The standard (ULE). I don't think the problem's related to the
scheduler: it shows all the signs of being an interrupt space problem.

I think you mean ACPI. This machine doesn't have an APIC.
To answer the presumed question: Yes, as I said above, the problems
only occur when I enable ACPI.
Since then I've also discovered that the builtin wireless card doesn't
work either. It's:
iwi0: <Intel(R) PRO/Wireless 2915ABG> mem 0xdfcfd000-0xdfcfdfff irq 10 at device 3.0 on pci3
iwi0: Ethernet address: 00:13:ce:46:28:49
After downloading the firmware, I can set IP addresses and such, but
I always get "no carrier":
iwi0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
ether 00:13:ce:46:28:49
media: IEEE 802.11 Wireless Ethernet autoselect
status: no carrier
ssid "" channel 1 (2412)
authmode OPEN privacy OFF deftxkey UNDEF powersavemode OFF
powersavesleep 100 txpowmax 100 txpower 100 rtsthreshold 2346
fragthreshold 2346 -pureg protmode CTS -wme roaming AUTO bintval 0
When I run dhclient on the interface, I get:
DHCPDISCOVER on iwi0 to 255.255.255.255 port 67 interval 6
DHCPDISCOVER on iwi0 to 255.255.255.255 port 67 interval 15
send_packet: Network is down
On the console I get the detailed error message:
iwi0: fatal error
This machine also has Linux on it, and the card works fine with Linux,
so it's obviously a FreeBSD-related problem.
