Two things:
- Please always cc relevant mailing lists when reporting a bug.
- With lockdep enabled (CONFIG_PROVE_LOCKING) you should get detailed
backtraces and lists of held lock when the kworker gets stuck. Can you
please reproduce with that option enabled and then attach the dmesg?
Thanks, Daniel
