Kernel messages over serial show CPU stalls some minutes later. I am attaching the full kernel logs below.
This issue is present in 6.16.7, however not in v6.17-rc6
A problem caused by the upstream commit of the change you mentioned above was fixed for v6.17-rc6, see 4de37a48b6b58f ("drm/mediatek: fix potential OF node use-after-free") or https://lore.kernel.org/all/20250829090345.21075-2-johan@kernel.org/
I wonder if that might fix your problem. It's currently scheduled to be included in the next 6.16.y release.
