Thanks for both logs, it helped.
However, it is rather problematic, because if you parse the hid-recording[1],
we receive:

 14.845206 ReportID: 3 / Confidence: 1 | Tip Switch: 0 | Contact Id:  0 | # |
X:    627 | Y:    364 | ... | Contact Count:    1 | B1: 0 | # 
 16.526414 ReportID: 3 / Confidence: 1 | Tip Switch: 1 | Contact Id:  0 | # |
X:      0 | Y:    306 | ... | Contact Count:    1 | B1: 0 | # 
 56.993181 ReportID: 3 / Confidence: 1 | Tip Switch: 1 | Contact Id:  0 | # |
X:    681 | Y:    316 | ... | Contact Count:    1 | B1: 0 | #

Which matches the evemu-record (finger up at 14.845206, then down in (0, 306),
wait 40 seconds, and move to (681, 316)).

So this means that it is either a firmware problem of the touchpad, or a I2C
error. Do you have any errors/warnings in your dmesg when this error occurs?

I am not sure it is a firmware issue because PS/2 works, and the PS/2 binding
should be using the same raw data than the I2C binding.

You might have more luck with a 4.5-rc4. Meanwhile, I'll try to talk to the
synaptics engineers about the issue.
