Please find the dmesg output attached. After noticing I also issued

$ sudo rmmod psmouse
$ sudo modprobe psmouse

to fix the problem.

It triggered today. I cannot remember the times before, but today I had
to turn off the system holding the power button for some seconds because
the system had crashed and the bug triggered the next boot. I do not
know if that matters.


Thanks,

Paul
