Sorry for top-posting and quoting this all, but the actual people

Adding more folks from a private report and

and for the new people, here's a lore link for this thread:

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.
Can the (partial) wchan backport possibly be dropped from v5.15.y until
someone figures out what exactly - if anything - is needed ?
Thanks,
