20230323.gitbcdcfbcf-0ubuntu1.7 hangs on boot with amdgpu

[Matthew Woodward]

[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.

This may be a very similar issue to https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2029396
