I don't know if it's the same issue; but there is another relatively similar issue that occurred very recently: bug #2070096
As I mentioned there, this commit is at least PART of the problem: commit 15c983d0cbb5a158eafb9cb88e6d8dfc4477d9c2 Author: Melissa Wen <[email protected]> Date: Fri Dec 29 15:25:00 2023 -0100 drm/amd/display: fix bandwidth validation failure on DCN 2.1 BugLink: https://bugs.launchpad.net/bugs/2059068 commit 3a0fa3bc245ef92838a8296e0055569b8dff94c4 upstream. IGT `amdgpu/amd_color/crtc-lut-accuracy` fails right at the beginning of the test execution, during atomic check, because DC rejects the bandwidth state for a fb sizing 64x64. The test was previously working with the deprecated dc_commit_state(). Now using dc_validate_with_context() approach, the atomic check needs to perform a full state validation. Therefore, set fast_validation to false in the dc_validate_global_state call for atomic check.
