However, we currently seem to have significant ACPI problems with Dell
laptops. I'm writing this on an Inspiron 6000 running 7-CURRENT, but
the same problems occur with 6.0: if I enable ACPI, timing goes to
hell, and some things just time out. There was a similar message a
couple of days ago from an owner of (I think) the latest Latitude
machine, which sounded even worse. My requests for feedback about how
to solve the problem have so far not been resolved. If you're
otherwise tending towards Dell, I'd suggest you watch this space until
there's some indication that the problems will be resolved.
Which scheduler are you using?
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.
Fine - I'm just offering the parts that I recall working around it for
me - if you are unwilling to at least try it, maybe someone else can and
report back so we know if it is or isn't related.
Also, have you tried disabling apic?
I think you mean ACPI. This machine doesn't have an APIC.
No, I meant apic. I realize it doesn't have one, but did you try
disabling it?
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)

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.
I also had problems with it. I ended up replacing it with a mini-pci
atheros card.
