Hi Len,

The problem does not exist, if I boot my PC and then
halt it immediately. If I login and use it for some
time, then acpi_power_off does not work.

Box 'X' is an Aopen MZ-915M, CPU is a 2 GHz Pentium
M. It is running Debian Sid, kernel is vanilla

Linux bugs 2.6.17-rc4 #1 PREEMPT Sat May 13 16:22:54 CEST 2006 i686 GNU/Linux

Old kernels don't work on this PC due to missing
hardware support. The first vanilla kernel that worked
reliably on this box (except for acpi_power_off) was 2.6.16.

Do you get any ACPI execution errors, etc. in the dmesg output after the system has been running for a while? I've seen this happen after the ACPI machinery gets into a bad state..
