After reading and trying allmost every single thread in the forum that contains the line "acpi_power_off" and also searching a lot on google that could fix it, i'm still stuck with it.
My setup
I have a pointer systems laptop (very recent) which works pretty well in linux so far.
Its a intel pentium mobile 2.0 Ghz cpu (centrino) with a ati x700 radeon mobility and all the other fancy stuff (wuxga tft, 2 gb ram and so on).
For the specs :

I'm using debian etch on it. With a kernel 2.6.16 that i build from source (for all my hardware to work)
Now the problem is when i issue a shutdown -h now command, the laptop hangs just before shutting down : onscreen saying "acpi_power_off called".
Waiting for about 30 minutes didn't switch it off, so it isn't turning off.
When i use the acpi=off in grub it also doesn't switch off but its just saying "power down" if i can recall good enough.
I think it might be some kernel option keeping it from powering off.
Disabling acpi is no option since i use cpufreqd for battery lifetime.
Even with acpi off it doesn't switch off anyway.
Any feedback that isn't written in the forum yet would be appreciated. so far now, i keep experimenting with some kernel options , and recompiling (lucky it only takes about 5 minutes on ths baby.. :P)
If you need to know more for analizing my problem, just let me know.
