@ALinuxUser:

There are 2 modes for touchpad, One is PS/2 mode, the other is smbus mode.

1, Old touchpad firmware:
touchpad can *not* work in PS/2 mode.
Only smbus mode is available

2, latest touchpad firmware:
Both PS/2 and smbus work well except after S3.
For now I didn't reproduce touchpad lost issue after S3 on PS/2 mode.
and dr_strangehate confirm PS/2 works well from S3 after updated to latest firmware.

From your log, touchpad firmware is old ( not updated to latest version).
But you used PS/2 mode, it looks like your touchpad worked on PS/2 mode.
This should not be expected on old firmware.

And for your log, it is not completed, it didn't show any issues of touchpad.

For smbus mode, there should be some firmware/driver issue, not found yet.
