Hi! After updating to linux-6.12.29, I see lots of "fail"-messages during boot:
May 19 23:39:09 LUX kernel: [ 4.819552] amdgpu 0000:30:00.0: amdgpu: [drm] amdgpu: DP AUX transfer fail:4
Bisecting for drivers/gpu/drm/amd had this result:
git bisect bad
2d63e66f7ba7b88b87e72155a33b970c81cf4664 is the first bad commit commit 2d63e66f7ba7b88b87e72155a33b970c81cf4664 (HEAD) Author: Wayne Lin Wayne.Lin@amd.com Date: Sun Apr 20 19:22:14 2025 +0800
drm/amd/display: Fix wrong handling for AUX_DEFER case
commit 65924ec69b29296845c7f628112353438e63ea56 upstream.
The system (Ryzen 3 5600G, latest BIOS) is stable so far but the error-messages are not nice to see. Thanks.

The fix "drm/amd/display: Avoid flooding unnecessary info messages" [1] is already queued up for the next -stable cycle.
cheers Holger

Already fixed here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... and on its way to stable.
