Unfortunately, I installed kernel 4.4.0-108 before seeing the relevant answer:
Kernel panic after update to 4.4.0-108-generic
I have already discarded the problematic kernel (purged) and switched to 4.4.0-109 and as of today to 4.4.0-112, but one problem still remains: the failure to reboot the system. Everything else seems to work fine, except from the rebooting operation.
Here, you can see a printscreen picture from the problem:
Any suggestions on how to handle this issue?
Thanks in advance!

For my home non-production 16.04 LTS machines I made the following decision:
I'll stay on 4.4.0-104 (and 4.4.0-103 as fallback) and 20170707 intel-microcode for complete and safe Meltdown and Spectre fixes which do not have side-effects (I do not mean speed here).
So I removed new kernels, reinstalled 103 and 104 and pinned corresponding packages.
Warning: do not follow steps below if you are using Ubuntu on production server or enterprise desktop.
Here are my steps to achieve this:
Remove new kernels
Install 4.4.0-104 and 4.4.0-103 (as fallback)
Install all 4.4.0-104 packages from cache for sure
Pin kernel-related package versions
When normal patches will be released you can simply remove pin and install corresponding packages with the following commands:
