Re: halt and poweroff do not shut the system down

When I run 'halt' or 'poweroff' (sysvinit-2.86) the kernel prints:

Halting.

Power down.
acpi_power_off called

But the system does not shut down. (The fans keep spinning, the LEDs
keep shining, the integrated LCD keeps displaying.) Basically, the
motherboard is still providing power to every component, as if the
power supply had refused to stop.

I noticed the following message at boot:

* The chipset may have PM-Timer Bug. Due to workarounds for a bug,
* this clock source is slow. If you are sure your timer does not have
* this bug, please use "acpi_pm_good" to disable the workaround

Is there any chance that the two issues are connected?
(It seems very unlikely.)

How can I tell whether the bug is fixed in my south bridge or not?
