Just had a win on this, while attempting to get ACPI timers going
If a value is written to /proc/acpi/alarm, then shutdown -h works!
This confirms my view that buggy bios firmware is the culprit.
On my system, I tried the command
echo "2006-10-02 15:40:00" > /proc/acpi/alarm
So it seems that the alarm must be set to a non-null value perhaps.
I havent seen if the kernel does anything different because of this
I am using bios 3.03. Its a bit of a wait till the 2.8 series kernels
