Public bug reported: [Impact]
20230323.gitbcdcfbcf-0ubuntu1.7 borks amdgpu during boot, it completely hangs the entire kernel on a RX 7900 XTX. Reverting back to 20230323.gitbcdcfbcf-0ubuntu1.2 made the kernel boot properly again. [Fix] Revert AMD firmware updates. [Test Case] Boot a machine with an affected AMD GPU. [Where Problems Could Occur] Machines with AMD GPUs might not boot or crash. This on Ubuntu 23.04 and 6.2.0-34-generic, but since the previous firmware worked I assume that the kernel version is not important here and it more is that the 1.7 update contains a firmware for the rx7900xtx that hangs it. Also booting to recovery and trying to enter non- graphical recovery mode worked just fine.
