Is flooding my syslog at a pace of on message every 200 ms !

This is really annoying.

Side note :

echo "disable" >> /sys/firmware/acpi/interrupts/gpe50

as root, permits to end syslog flooding.

[Joseph Salisbury (jsalisbury)]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Alex Garel (alex-garel)]

FYI, still got it with "4.13.0-21-generic".

Sorry, but I still won't be able to test on the upstream kernel this week…

[Alex Garel (alex-garel)]

Ok I finally got the time to test it on upstream kernel.

I have the same flooding of /var/log/syslog about every 200 msecs with:

I also have this issue with Cosmic (4.18.0-13) and also with the latest upstream kernel:

[Alex Garel (alex-garel)]

I can confirm on my side that it's still there after I also upgrade to Cosmic.

[crt (crt-mori)]

It appeared for me after upgrade to Cosmic (did not have it before). And on both desktop PC and laptop.

[Peter Curtis (pdcurtis)]

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. So whenever there is a log message coming in, rsyslog will be started on demand. The unit is named syslog.socket. So to stop the rsyslog service one needs to stop both units:

systemctl stop syslog.socket rsyslog.service

or completely to disable logging from the next boot by:

systemctl disable syslog.socket rsyslog.service

None of these are satisfactory long term solutions
