Without attaching the full journal, on failing boots I find this kernel bug:

Thank you so much for this stacktrace. This looks like a problem that we recently fixed in the upstream kernel. Yesterday, I backported the patch into out stable branch. So this problem should be fixed in the next kernel update. Sorry for all the inconvenience with the graphics stack in recent weeks. We try to modernize it, but it's not a trivial issue. -- You are receiving this mail because: You are on the CC list for the bug.
