ACPI Problems with Kernel 2.6.3 on Compaq Armada M700
Hi;
I have been running a mixture a testing/unstable on this notebook for
about a year with almost no problems. I recently upgraded to the 2.6
kernel (kernel-image-2.6-686) and since then having been having random
but fairly frequent keyboard lockups. The keyboard becomes unresponsive
to any key presses, while the mouse continues to work correctly. If I
log out of gnome, the system appears to hang with a flashing cursor in
the upper left hand corner. Usually I end up having to unplug the system
and remove the battery to restart. The only thing I see in the logs is
this in kern.log:

Any ideas?
