Hi,
I'm seeing this oops on my P4 box running 2.5.66-bk12 + ACPI when
shutting it down (copied by hand):
Power down.
acpi_power_off called
Debug: sleeping function called from illegal context at
include/asm/semaphore.h: 119
Call Trace:

This is not 100% reproducible. When using ACPI, the machine is *never*
able to properly shut it off (only APM is able to turn the machine off).
