apport information

** Description changed:
I run Ubuntu 17.10 (Kubuntu) on a Thinkpad Yoga260 notebook. 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).
