Touchpad stops working for a period of time

[Rob Aldridge]

Occasionally the touchpad will stop working for a period of time, the mouse cursor disappears but the touchpad buttons still work. The keyboard and touchscreen still work normally.

Eventually after a few minutes the touchpad starts working again.

The system may need to use elan_i2c, please test this kernel:

Thanks Kai-Heng,

I tested the Kernel from the link in #3 but the touchpad did NOT work at all.

Cheers,
Rob

Can you please test latest mainline kernel again? There are some new elan_i2c fixes.
