From the log on the mysql server restart:

Could you report (after you checked there is nothing confidential in it) your mysql log and syslog files from:
/var/log/mysql.err
/var/log/mysql.log
/var/log/syslog

If you want to shrink them you can drop all but the last 5 minutes before/after that happened.
Especially on the syslog be aware that it might already have rotated forward so you might find the content in /var/log/syslog.*

With some luck there is something listed what is actually failing almost instantly.
I'd expect something in your config that is now failing with the newer version, but without logs that is only guessing.
