I'm not that experienced with updating Linux kernels, but after reading that 4.10 had firmware improvements for my new laptop (intel Kaby Lake processor) I thought i'd give sparkys 4.11.2 kernel a try. The upgrade itself went well however programmes become unresponsive when trying to run them and the system fails to shutdown/reboot. For now i've gone back to the standard current kernel, but would like to get this one working, if possible.

Have you looked at your systemd logs?  Digital ocean has some good pages about using journalctl.  journalctl -b -1 | tail will give some info about the shutdown/reboot process of the last log.

Thanks paxmark1, thats a great article and i've now setup persistent journal logging. I reinstalled the sparky-kernel and this is the journal output:
#8:01 - 8:02 seem to be only with this kernel?

I am not a kernel guru, I'm on 4.09.  What was the specific journalctl command for your output? Beginning or end? For showing the last lines for a stalled or frozen shutdown also "journalctl -b -1 -r" will allow you more than the ten lines of "journaltctl -b -1 tail" - it scrolls.  I am not sure what kworker does, oh it is a kernel function.  Good Luck.   I look at my logs a lot less after my not having a sid machine around.

# ok, it took a few days of tinkering but I can now run the latest sparky kernel (4.11.3).
Apart from fixing a few firmware issues, I found an entry in my syslog "nouveau 0000:01:00.0: unknown chipset (136000a1)". After a bit of research I tried adding "nouveau.modeset=0" to the GRUB options and voila! Hope this helps someone else in the same trouble..
