System hangs/freezes at reboot


Every time I reboot or shutdown my system hangs

Linux mint 17.3 64bit
Updated kernel to 4.4

Is there a log to find out where my system hangs


Problem fixed…

Changed kernal to 4.2


OK I did something again and I am facing same problem again

Help me fix it


Stop upgrading to unstable. Format and use Debian testing version.


alt+sys req+b works

but is there any alternative command that i can use
so that i can script my own restart command


I don’t think upgrade caused the priblem

Recent activity was setting up the printer
Update rc.d ccpd defaults 20

Which got me an lsb header warning
