Package: firmware-amd-graphics
Version: 20230210-5
Severity: important
Tags: patch upstream
X-Debbugs-Cc: linux.footwork855@simplelogin.com

Dear Maintainer,

Rembrandt GPUs in combination with certain Parade TCONs are suffering from
irrecoverable system hangs when PSR is enabled (as it is by default). There is
a Gitlab ticket for this issue here:
https://gitlab.freedesktop.org/drm/amd/-/issues/2443#note_1966723

An upstream firmware patch has landed which mitigates the issue:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/commit/amdgpu/yellow_carp_dmcub.bin?id=9dbd8ec28fd810e5f4f9da41452aba74896a5564

Please consider backporting this patch to Bookworm. Thank you very much.
