Issue/Bug Description: I experience essentially the same as bug pop-os/pop#3115 (recently closed due to a grumpy user). When waking, the computer fans rev up and it's clear the CPU is 100%. Logging in from another machine, 'top' usually shows that logging is busy, along with Gnome, and sometimes a Firefox tab. This freeze-from-wake occurs every few days. The system goes into an infinite loop writing syslogs. Killing gnome-shell from another machine fixes it. Below are some recent logs around the last time. This is where the problem seems to begin, then the last few lines get very repetitive. (My /var/log/syslog file has 2GB that is mainly copies of the JSAPI log and stack trace.) Hope this helps.

If the logs are not useful enough, feel free to close this bug. I'll open a new one if I find something better to share.

I can create a PR that might help if you can test it.

Possible fix may be built locally with make / make install, or by adding the staging branch after its debian package is built

sudo apt-manage add popdev:freeze
sudo apt update
sudo apt full-upgrade

After PR is merged, staging branch must be manually removed

sudo apt-manage remove popdev-freeze
