Adding more folks from a private report and
https://bugzilla.kernel.org/show_bug.cgi?id=215031
and for the new people, here's a lore link for this thread:
https://lore.kernel.org/stable/YZV02RCRVHIa144u@fedora64.linuxtx.org/
FWIW, earlier bisection pointed to the stable backport of
5d1ceb3969b6b2e47e2df6d17790a7c5a20fcbb4 being the primary culprit.
At first glance it seems to me that the problem with -stable is that an
unvetted subset of the wchan refactoring series landed in -stable.
