--- Comment #3 from freddyreimer@comcast.net --- Update. Roughly around the time of the last update to this, I manually added that fix and it was working out for me. However, I ran some updates to both mesa and the kernel itself and now it appears the issue is back.
I have updated this issue with my current specifications. I'm on the 5.5.2 kernel now, with my package manager reporting the mesa version as 20.0.0_rc1. llvm is on 9.0.1.
I'll also add in an attachment with a more recent dmesg tail. I did try checking to see if I could manually re-add the patch to the file again, but it looks like those lines of code are already there, yet this issue still persists.
