If these machines are P4-based, then I bet they do have local APICs.
However, if the BIOS boots the kernel with the local APIC disabled
on a P4, we (apic.c) don't try to enable it. The logic behind that
is that "modern" BIOSen _should_ boot with it enabled, unless they're
horribly broken.
So apply the patch below and try the "can we get the machine to hang"
checklist again.

Local APIC disabled by BIOS -- reenabling.
Found and enabled local APIC!
And now /proc/cpuinfo and cpuid both show APIC support.
Removed/replaced power, triggered lid-switch/battery-status/etc with no
issues. (The only thing that caused trouble was Fn-F10, the "eject cd"
button. Never tried it under Linux before, and the cd isn't in it at
the moment anyway, so I'm betting thats unrelated. But it did cause a
lockup that even sysrq couldn't recover.)
Not 100% clear on what the APIC does, but I'm not sure its doing it ;)
PCI: Using ACPI for IRQ routing <-- shouldn't this be missing if the
APIC is in use?
(Full dmesg attached, for those who are curious - the unknown-scancode
is for the various laptop buttons - bright/dim, vol, media, battery,
etc. Except for the volume buttons the only ones that work are the ones
that directly hit the hardware, ala bright/dim.)
Also, for others with an I8500 who might read the dmesg log, don't get
excited; thats not the wireless card they sell (Broadcom 802.11g) its
the older one (Orinoco 802.11b). They'll sell you one for about $70,
goes right in in place of the unsupported one.

Nope. local APIC != I/O APIC. Disable ACPI, or enable IO_APIC (and hope it's there).

I'm betting it doesn't have an IO-APIC (its a laptop, no SMP, etc) ..
any way to tell if the APIC is working/enabled? (For that matter, all
google could tell me about was the IO-APIC, which is handy to know but
not particularly helpful here.)

Attached (I pulled out the service tag and express service code, both of
which are local to the individual device.)
Also, not sure what (if anything) would be different with the A01 bios;
their changelog seems to focus mostly on fixing a sound bug (which,
unfortunately, I didn't have until -after- the fix... sigh.)
Their changelog is online ( support.dell.com 'small business' ->
'Inspiron 8500' -> 'FlashBIOS updates') but there's not much to it.

OK, there's good news and bad news. After doing that and lopping out the
dmi_scan.c blacklist entry, we get these msgs on boot (diffing against
a dmesg from before the above:

So yes Virginia, there is a local APIC on the C840.
Now the bad news - out of 7 or 8 tries, the above was the only boot that lived
long enough for me to get a single-user prompt and do a dmesg into a file.
That try hung about 10 seconds later. It never hung at the same place twice,
and always hung hard enough to require the "power button for 5 seconds to
poweroff" sledgehammer. The common factor seemed to be hangs while talking
to the IDE drive - while mounting /, while checking the partition table,
etc.
One question - in apic.c, I see where clear_local_APIC() is called in
init_bsp_APIC(), connect_bsp_APIC(), and disable_local_APIC(). I however
don't see where/how it's called in the init_local_APIC() codepath, nor can
I convince myself that it obviously *shouldn't* be called...

..and it gets better. Not sure what the exact problem is (updated DRM, X
etc) but Fn-F8 (CRT/LCD) hardlocks. With the no-APIC kernel (same new
DRM and so forth) it just hesitates (not sure if it works or not,
haven't got a monitor handy.) It worked (or at least didn't lock up)
when I initially tried it, but now I can reproduce it well before X
comes up.
Looks like it should be dropped from the whitelist :( (To recap, this
is the Inspiron 8500 w/ A02 bios)
