In this ( ) the same behaviour is observed on a T14s (AMD) (which shares its motherboard with the X13 (AMD)) running 5.7 mainline on Ubuntu. I was able to reproduce this on Manjaro Linux and Artix, so this must be a general kernel issue and not distribution-specific. I am running a fully updated Fedora 32 installation, kernel `5.8.86_64`. Oddly the physical address `isa0060/serio1/input0` corresponds to the Touchpad and not the TrackPoint (see attached output of `cat /proc/bus/input/devices`) Therefore I assume, that the TrackPoint only loses sync if it is actively used. If only the Touchpad is used, the above message does not appear at all, the Touchpad is working fine as expected. psmouse serio1: Touchpad at isa0060/serio1/input0 - driver resynced. psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 When this happens (often but not always) the following output is printed to dmesg:
This happens around three times in five minutes, without any noticable pattern, but consistently. Sometimes when using the TrackPoint on a Thinkpad X13 (AMD) the mouse cursor jumps to a corner or edge, as if the speed has been increased to infinite for a fraction of a second.Īfter that, it is usable like it was before.
