I'm hoping I'm just doing something wrong, but I don't see anything
right offhand.
Hard to do anything wrong, i.e., you just have to enter "crash".
With a kernel that new, it certainly could be shifting sands syndrome.
It did get quite a long way before failing. I wonder if something's
changed upstream associated with the pid_hash code? Can you verify
that the tt->refresh_hash_table gets set to refresh_hlist_task_table_v2()?
If the system is accessible to me (reply offline), I'll be happy to
take a look.
