The trackpad hangs regularly, typically after a few minutes of use. dmesg reports "lost sync bytes". Interestingly, this error already occurred in 16.04 (there are many reports about this, e.g. https://askubuntu.com/questions/922092/lifebook-e546-touchpad-on- ubuntu-16-04), but my notebook works fine with 16.10 which I used for about a year without any problems. Now that I updated it to 17.10 it occurs again. Both 16.10 and 17.10 are now installed in parallel, but the error only manifests when I boot into the latter. I have tried proto=imps and proto=bare (module psmouse), but this does not make a difference. I report this here because this might be some kind of regression (or coincidence).
