Comment 3 for bug 2008951

System went into reboot after reboot after each sign in. Only way I found to get out of it was to select Ubuntu advanced options at boot screen, and select to rebuild grub boot. As a result I have attached more files than requested after running -

journalctl -b-1 > prevboot1.txt
journalctl -b-2 > prevboot2.txt
journalctl -b-3 > prevboot3.txt
journalctl -b-4 > prevboot4.txt
journalctl -b-5 > prevboot5.txt
