The first warning from kthread_stop() indicates that the task has no proper flag, but the code creates it certainly via kthread_run(). The NULL deref after that indicates the same cause, too. Could you check the debug kernel to see whether we can catch something beforehand? -- You are receiving this mail because: You are on the CC list for the bug.

There is nothing else obviously failing. Maybe the debug kernel can give some results regardless. -- You are receiving this mail because: You are on the CC list for the bug.

I get no messages about this because the log has overflown and there is no obvious way to get to older messages with journalctl. -- You are receiving this mail because: You are on the CC list for the bug.
