Laptop APM & ACPI
I currently have a problem with an AOpen 1845 Laptop. When ACPI & APM
is turned on, the mouse plugged into the PS/2 port will misbehave
occasionally when the machine gets a bit busy. Turning APM and ACPI off
at boot time solved the problem but now the power management is gone.
Whenever the mouse misbehaves I see the following messages showing up in
kernel: psmouse.c: Mouse at isa0060/serio2/input0 lost synchronization,
throwing 2 bytes away.
I'm currently running kernel 22.214.171.124. I saw that there was in the
latest 2.6.11 kernels a lot of cleanups with the serio subsystem as well
as quite a few updates w.r.t. timings with the mouse/touchpad. The
notebook does not have an option to turn off the touchpad so the
Synaptics Touchpad/PS2 port mux is constantly on. Have been through
most combinations now and none seem to fix it.
With APM/ACPI off things are fine... I'm not sure from looking the
kernel source since about 2.6.0 where to start hunting for this problem.
Tnx & Bi
