Has there been any progress on this.
I still have the same problem on both kernel 4.15 and 5.4.
I still have to modify logrotate to limit logging or more recently I
have tried stopping the logging of any errors which was not as simple as
I expected as rsyslog uses socket activation under systemd.
I have the same flooding of /var/log/syslog about every 200 msecs with:

I can also confirm that the 3.19.0.49-generic kernel solves the problem
for me.

I have carried out some more comprehensive tests using the kernel in #4 over

quick test showed. Most of the rather bizarre behaviour has gone include the

I also have a similar problem which does Not seem to be solved by the
patched kernel although the perf report looks very similar and plugging
in a USB device clears the problem. The starting and inhibiting of the

Christopher Penalver, life is too short to proliferate bug reports when
there is an existing one with all the background. In my opinion what is
needed is crosslinking and consolidation rather than proliferation so a
