No, as i said this is not the reason, and we've already fixed it properly
You can see it here:
https://github.com/t2linux/linux-t2-patches/blob/main/7003-amdgpu-add-support-for-5K.patch
(Adds 5K support and fixes the boot issue).
And for the 16,1 issue (i assume), the only fix is
https://lore.kernel.org/all/20261024162109.307247-1-dev@deq.rocks/
The PPTables provided uclk clock speeds is wrong, thats what causes the issue,
initializing UCLK in post_init wont solve that.
