Hi folks,

I am encoutering ACPI related problems with 2.6.0-test3 and my Acer TravelMate
800 LCi. Everytime I try to send it to suspend mode ('echo 3 > /proc/acpi/sleep'), 
the following lines appears in syslog and the box does not suspend at all:

After doing the same command another time, I saw the following in syslog after
reboot (the box locked up hard when I tried to start X):

I would also have tried 2.6.0-test3-bk5 but somehow the ACPI menu disappeared
with that version and .config does not even have something ACPI specific in it.

I can verify this, I will try to capture my OOPS somehow as my machine 
locks up hard before I can do anything.
For you info, the 800 LCi is a centrino based computer.
