Plausible. The sheer volume of crashes I've started seeing in the last 24 hours
since adding those small features to trinity are making me really suspicious.
If I had this volume of crashes reported to me by a Fedora user, I'd be
suspecting their hardware ;)
Tangentally related: We have a *ton* of weird bug reports against Fedora
that have been open for a while that look like random memory corruption
(linked list corruption, 'bad page table' scribbles etc).
I'd *love* to think that the bugs I'm now seeing are related, on the off-chance
we can finally get some resolution on those.

My kernel-hacker hive-mind implant is working. Just started a rebuild with that
enabled.
Had slub debug already.

Yep.
