Comment 91 for bug 34501

After making a dist-upgrade from Ubuntu 10.04 to 10.10, I got this bug happening on my Asus Aspire AS1410 laptop. About 5-10 minutes after system startup (actually, it seems to depend on actual activity on the touchpad/keyboard), the mouse and keyboard start to act erratically (mouse becomes laggy and keyboard either starts typing single random characters, as if the corresponding key was stuck, or simply stops responding). After that, both touchpad and keyboard become completely stuck and don't respond to any input at all.

An external USB mouse is still usable though, as well as the power-on button, and with that I can still do some limited actions. For example, put the system to standby. After resume it works again, but only for several minutes.

This coincides with the following messages in dmesg:

[ 97.862555] psmouse.c: TouchPad at isa0060/serio1/input0 lost synchronization, throwing 5 bytes away.
[ 98.477125] psmouse.c: resync failed, issuing reconnect request
[ 101.575447] Unable to query Synaptics hardware.
[ 102.812351] i8042.c: Can't write CTR while closing AUX port.
[ 103.839744] i8042.c: Can't write CTR while closing AUX port.

My kernel version is: 2.6.35-22-generic. Setting i8042.nomux=1 and i8042.reset=1 gave no improvement.

It's curious, that it seemed to be totally OK in 10.04, or at least not as bad as it is now. And it clearly started right after the upgrade to 10.10, that I am sure.

I am going to try to revert the system to an older kernel or try disabling sensors.
