Freezing Randomly After Sleep

[618C]

Bought a new Darter Pro from System76, installed Ubuntu Budgie 18.04. I've been experiencing random freezes waking the laptop from sleep.
When I say random, I mean it only happens a small percent of the time. When it does, it's usually 5-10 seconds after waking when it does freeze.

I can't switch TTY sessions, mouse and keyboard seem unresponsive. Hard reboot seems to be the only thing I can do. I've opened a ticket with System76, but wanted to know if there's anything else I can look into to resolve the issue.

Linux bullseye 5.3.0-7625-generic #27~1576774585~18.04~c7868f8~dev-Ubuntu SMP Thu Dec 19 20:37:32  x86_64 x86_64 x86_64 GNU/Linux

Logs shown right before I gave it a hard reboot but after I woke it up and it froze.

Have you installed the System76 drivers?

With an AMD cpu desktop computer, I've experienced similar wakeup problems with Ub 14.04, 16.04, and for a short period with 18.04 after which it stopped.

I never could find a fix. The problem seemed to mostly occur shortly after Ub updates. I wound up using qt5-fsarchiver to backup the o/s after a period of no problems - that is the state of the o/s wasn't having the problem. I reduced doing updates to once or twice a month. If the wakeup problem reoccurred, I would recover the saved o/s that was running ok, use it for a while, then update. Usually, I'd get a stretch of usage without the wakeup problem recurring and once I felt like I had a good o/s state, I'd backup that one.

Hope that helps.

Add "i8042.nomux=1" as kernel parameter in /etc/default/grub, update grub and see if that works. It worked for me.
