Hi,
I've installed ArchLinux (x86_64) today on my new HP 8740w laptop (Core-i7 Q720 + nVidia quadro FX 3800m).
With kernel26-2.6.34-1 from testing.
kacpid but 96.5% of the first core all the time as reported by ps aux.
I've upgraded the BIOS.
I use Arch on another laptop (HP 4510s) every day with the same kernel without problem.
Result of ps aux:

EDIT:
There is a know bug in some HP laptop BIOS. Kernel 2.6.35 (git version) resolve this issue, but it need to add the line "echo disable > /sys/firmware/acpi/interrupts/gpe01" in /etc/rc.local
I'm waiting for the Arch version of 2.6.35 now :-)

I've tried to downgrade the kernel with 2.6.33 in Core. Same problem.

I am having the same problem hp 8540p I tried using 2.6.35 and the issue issue persisted. I have seen this reported elsewhere and none of the "workarounds" seem to resolve our problem. I am continuing to investigate but if this problem isn't corrected I believe it will damage our hardware as the acpi control system is completely borked.

Hi rippleAdder,
Update your BIOS as this bug come from the new HP bios on some laptop (mainly EliteBook) and reset to factory setting. There is a problem with "run always the fan whith AC adapter connected" or something like that (i can't look at my bios now because i'm compiling a big software).
The patch was applied to the 2.6.35 tree after the rc3 release candidate.
Please try this patch with the kernel source 2.6.35-rc3 with the last git patch (i'm using the 20100625 version) and add tjhis patch (found somewhere on the kenel bugzilla):

I've made a PKGBUILD file (tweaked from another kernel release) for this. Please ask if you need it. It's not very good but do the job.

I installed kernel26-git and the main problem seems to have stopped. Now and have issue compiling modules specifically alsa snd-aloop and I can forsee other issues as there is no matching header package for this kernel build. I have no luck flashing the bios from usb but I could be doing it wrong.
Offline
you can remove kernel26-headers with pacman -R. The kernel26-git pkgbuild install all the headers file in /usr/src.
Have you tried to reflash your bios with freedos?

Kernel .35 don't help me, but I'm think I solved this problem in my Intel Atom-based system.
From https://bugs.launchpad.net/ubuntu/+sour … comments/9:
I disabled in the BIOS "fan controlled from operating system".
My BIOS allows to set a fixed speed (from 50% up to 100%) or speed controlled by operating system.
Now I have put the speed fixed to 50% and this is fixed fixed fixed.
