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.

Cheers

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.

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.
