after which I can do nothing but forcibly power-off (really, Windows 95 experience).
I'd be happy to hear if there is any workaround. Meanwhile, can I do anything to do a clean shutdown (switching VTs or trying to kill X does not work, system is totally unresponsive)? Thanks in advance

A kind user on this reddit thread suggested that this may be cause by NVIDIA KMS (which I have enabled). I'm experimenting with turning it off.
That's probably it - no crashes since disabling nvidia's KMS

Did a install earlier today, can confirm. Saw the info was already on wiki.
I possess a device, in my pocket, that is capable of accessing the entirety of information known to man.
I use it to look at funny pictures of cats and to argue with strangers.

Indeed, no crashes for the last 6 hours. Marking as SOLVED.
