niclas.kroon, the next step is to fully commit bisect from kernel 4.2 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your understanding.

Unable to move around the desktop. Cant find anything in dmesg-, xorg- or syslog- logs that seems to cause it. A reboot solves the problem temporarily but occures soon again so something is borked.
