I would say the below is stacktrace of another thread:
Here we can see that kupdate won the commit races
and performs write_logs, whereas at your screen we
can see a stacktrace of the final sync, which is waiting
(I guess) for this atom to be committed. I see nothing
criminal here. So we need to figure out why the commit
takes so much time. Unfortunately sysrq-t dumps aren't
able to provide such details, I'll think how to do it with
your assistance.
Good work!
Thanks,
Edward.
