syslog filling up with the below error trace while gaming

System:

  • 5.4.0-39-generic #43-Ubuntu
  • AMD Ryzen 7
  • AMD 6600XT
  • 32GB RAM
  • ASUS B450 Plus

Background:

I have been running this Ryzen 7 and same board with an Nvidia 970 in Fedora 31 without issues. When I bought the AMD 6600XT about 4 days ago, Fedora driver support by AMD is not being offered so I installed Ubuntu 20. This is a new install with newly updated kernel and newest AMD drivers. I have been using this setup for the last 3 days without issue. My guess is that it took roughly 3 days for my issue to occur.


Issue:

I was playing an older game in with Proton and I got a system alert stating I was almost out of hard drive space. I checked the volume and saw my syslog was over 100GB and the concatted file was over 45GB. I cleared my logs to save up space and watched my syslog file as I went back to gaming. I kept seeing this error over and over. The harder my system churned, the more I got the following:

Replication:
I am able to replicate this with any game that activates the display, including Linux games not using wine, thus, I don’t believe it is a wine issue.

Edit:
Removed the side note, unrelated


Question:

Is this a known spam that can be turned off or something indicative of a more serious issue? The rig seems to be operating fine, just need to get the system log issue sorted.
