Exciting! Thank you so much for your help mate, it’s very much appreciated.

I did try kernel 6.6 without either patch before installing the new one, and I can confirm that the issue was still present on that version.

With the new patch though (after adding a comma to the end of each .ident string), everything is working as expected.

Either way, this did it! Thank you so much!

I believe that the issue might be that the amdgpu driver is too new, judging by this string of errors:

So if this doesn’t end up working, I’ll definitely look into the pinning thing, because 5.10 seems like my best shot.

Figured I’d do the pre-setup before I went to bed, so I’ve run the grep command and put the board_name from that output such that the patch now reads thus:

I’ll report back with the results when I’m able.
