As mentioned before, I get the same error with a monitor connected with DP to a Lenovo ThinkPad USB-C Dock Gen2. My Laptop has an Intel i7 10510U no additional graphics card. I am using Debian testing with the provided kernel.
During this my notebook monitor is blinking. This setup worked for around four weeks when suddenly these errors occurred.
Can you bisect?
