This may capture messages from before the log gets going:
Firstly tell systemd to keep the journal
sudo mkdir /var/log/journal
The fact that the directory exists tells it to put stuff there.
Reboot into the failing kernel
Rebbot into the good kernel
Immediately run
journalctl -b -1 > ~/tmp/journal.txt
then in /tmp/journal.txt there may be something useful

Once this problem is sorted remove the /var/log/journal directory again.
