Does booting with i8042.noloop=1 help?

Yes, this option has fixed the issue.

See updated Xorg.log, dmesg and hwinfo.

patch trying to solve the pegatron problem

Hi Andrey Ponomarenko,

would you mind trying the attached patch and then boot the new kernel without any i8042 parameters? If this works correctly, you can use your touchpad out of the box in the newer kernels.

Thanks!
