According to this email: https://lkml.iu.edu/hypermail/linux/kernel/2401.3/05636.html a very similar issue has been fixed recently: "So we had a number of small annoying issues in rc1, including an amdgpu scheduling bug that could cause a hung desktop (that would *eventually* recover, but after a long enough timeout that most people probably ended up rebooting instead. That one seems to have hit a fair number of people." Therefore, the fix for this bug may be this commit which has been included in Linux v6.8-rc2: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.8-rc2&id=bc8f6d42b1334f486980d57c8d12f3128d30c2e3
