[ltp] T42 won't power off after shutdown/halt/poweroff

[J.V.]

Hi all,

I'm having an issue that many people seem to be having as well but
I'm having trouble finding a solution.

I can't get the system to turn off after a shutdown -h, halt, init 0,
or poweroff.  The screen turns off after a message displays about
powering off but the fan is still spinning and unplugging the AC
makes it beep.

I tried various combinations of the following lilo parameters:

   apm=off
   acpi=on
   acpi_sleep=s3_bios
   noapic
   nolapic

when use nolapic, it hangs during boot at:

   Calibrating delay loop...

Here's some pertinent information about my system:

Thinkpad T42 (2378-FVU)
Mandrake 10.0 w/kernel 2.6.8.1-2mdk (from cooker)

This hard drive was originally in a Thinkpad T20 which used APM just
fine (even screen blanking (Fn-F3) worked) but there seemed to be lots
of problems with APM on the T42 so I switched to ACPI (if I did it
correctly).


Here's some interesting processes:

# ps -eaf | egrep -i 'apm|acpi|power'
root         5     3  0 20:21 ?        00:00:00 [kacpid]
root      2789     1  0 20:22 ?        00:00:00 /usr/sbin/acpid


Here's the kernel configuration variables from .config:
