Problem with acpi_power_off

Problem with acpi_power_off

[Charles Kendricks]

I am in charge of several linux 2.6.4 systems with Dragon P4I875P 
motherboards.  I am relatively new to acpi so my question might seem a 
little elementary, but I can't seem to get my systems to power off 
consistently when I issue an init 0.  It seems that all of them will 
power down sometimes, and at other times the same systems won't power 
down.  Once powered down I have no problem (at least not yet anyway) 
waking the systems back up.  What can be causing this inconsistent 
behavior?????

there are two things you may try:
  1. If your system does not use the local APIC you might build a kernel
   without "Local APIC support on uniprocessors" CONFIG_X86_UP_APIC
  2. do not use the rtc-module "Enhanced Real Time Clock Support", but if
   you need the generic RTC CONFIG_GEN_RTC instead.
And please report back, if one of this things solves your problem.

As some of you may remember, this is what solved the problem for me some
times ago.  However, in the last few days, I noticed on 2 occasions that my
laptop did not power off.  The only thing I changed was playing with usb
stuff, making some of it as modules and not.

The worrying thing is that it is not consistent.  At least I haven't been
able to see the pattern yet (as it only happened twice).  Will try to
figure out and report back if/when I do.

Fred

the same thing happens to my Abit mainboard, yet if I press AltGR-Print-O
the pc *really* shuts  down, so I guess the real power_off() isn't being 
called
during init 0.

Gentlemen, thank you for the tip, but I already pass "noapic" to my boot
command in grub (my system clock was originally running at 2X normal
speed)....shouldn't that take care of the CONFIG_X86_UP_APIC module in
the kernel, and if so, is there not another argument that I can pass to
the boot command in grub to take care of the Enhanced Real Time Clock??
I'm not looking forward to having to rebuild the kernel on 16 linux
boxes :^(
