fwupd is consuming 100% of CPU in an upto date Ubuntu 16.04

[Kasun Siyambalapitiya]

Even though this bug is reported [https://bugs.launchpad.net/ubuntu/+source/appstream-glib/+bug/1591868] and marked as fixed, I am having the same issue on a up to date Ubuntu 16.04 system (as you can see in the attachment). Rebooting doesn't fix the problem.

Thanks.

Experienced the same today morning in upto date Ubuntu 16.04 on Thinkpad X1 carbon 5th gen had to run `killall fwupd` to get rid of it. Please take measures to fix this ASAP.

Status changed to 'Confirmed' because the bug affects multiple users.

Same issue happens on my Thinkpad x1 carbon 5th laptop. I just installed Ubuntu 16.04.3 alongside with Windows 10. fwupd randomly consumes 100% of the CPU but I didn't find any special err in my syslog. It just happened randomly without a signal (usually a short after booting), and I don't know how to reproduce it.

This problem can draining my laptop battery, therefore I have to disable fwupd.

I have the same issue. This happens after I login. I am running ubuntu 16.04 with 4.13.0-041300-generic kernel on a Thinkpad X1 Carbon (5th gen).

[gabrielsz87 (gabrielsz87)]

Thinkpad x1 carbon 5th gen users: I upgraded to 17.04 and I don't have the problem anymore. It also fixed other minor issues I was having.

@gabrielsz87 Ubuntu 17.04 is not a stable released, I need to stick with the latest LTS version which is 16.04, is there a way to get that specific fix installed to Ubuntu 16.04 ? Thanks

I also have the same issue. By killing fwupd I was able to temporarily stop the CPU usage. Manually restarting does not cause CPU usage to spike up again. Attached is the output of fwupd after manually restarting with,

> sudo /usr/lib/x86_64-linux-gnu/fwupd/fwupd -v

Here's my system info,

Same problem with Lenovo ThinkPad X1 Yoga LCD (2nd. Gen.) running on up-to date Ubuntu 16.04

Saw this problem again this morning. I was able to capture the following snippet from /var/log/syslog. The final line repeats forever,

Ping on this issue? It happened again today.

[Fredrik Öhrström (oehrstroem)]

I just allowed the automatic update to do an update. After the required reboot,
then fwupd goes 100% cpu.

I have the same problem. Interestingly it is also on a Thinkpad. A Lenovo Thinkpad T440s

Hi All,

Those affected by this, can anyone readily reproduce it still?
If so, can you please try to upgrade to the version of fwupd in xenial-proposed to see if it persists?

Thanks,

[Max Müller (hutsch)]

Hi Mario,

the upgrade solved the problem for me. I am using a
ThinkPad X1 Carbon 5th Gen.

[Mario Limonciello (superm1)]

Thanks for confirming. I'll close this issue then. If it happens again for anyone, please open a new issue .
