Just a follow up, this also seems to happen after booting, depending on
the modules that are loaded, it looks like. I blacklisted a few more
modules and now my system consistently doesn't stay up for more than a
few minutes [1]. (I am trying to make it idle properly, but of course
wasn't  counting on that causing crashes more often. :-))

In my case, commenting these in my modprobe blacklist made crashes go
away (but that could simply be because my system was finally idling with
these modules blocked and unblocking them makes it not idle...):

Not sure if it helps...

Cheers,
