Touchpad freeze after suspend (lost sync)

[mh]

On a Lenovo 300e (Winbook w. touch), after suspend (after reopening the screen) a problem occurs with the touchpad. With original and latest bios, on Ubuntu 18.04 and 18.10. Pointer control via the pen on the touchscreen works right away but the touchpad initially fails to activate after suspend. The problem is logged in the syslog:

The above sequence occurs a large number of times. Then, after a minute or so:

Nov 13 18:10:30 laptop kernel: [47070.218237] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6

Nov 13 18:10:31 laptop kernel: [47070.990556] psmouse serio1: Touchpad at isa0060/serio1/input0 lost synchronization, throwing 3 bytes away.

After which the touchpad works fine. If further info is required please tet me know how to obtain it.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.20 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

It is on a new laptop (lenovo 300e winbook), not after an upgrade. I've had 18.04 and 18.10 installed. The HW is OK (problem is not there with windows 10). The touchpad is

Milan, can you please file a separate new bug? It's a different case for HP laptops.
