--- Comment #6 from Dennis Busch (dennis-busch@....net) ---
The bug report I linked to in comment 3 mentioned two patches (
https://patchwork.kernel.org/patch/10181165/ and
https://patchwork.kernel.org/patch/10233617/ ) but neither of those appears to
have been applied. I would stick to the last working kernel version for now
(for me that is 4.14.19 as mentioned in that other bug report) and keep an eye
on https://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git/ to
see if anything familiar looking pops up which suggests that this particular
problem was fixed ( maybe it already was but I am unable to determine for sure
as I do not fully understand the issue, just have a hunch the problem is/was a
locking issue in the RCU system ).
