Title:
20230323.gitbcdcfbcf-0ubuntu1.7 hangs on boot with amdgpu
Status in linux-firmware package in Ubuntu:
Confirmed
Bug description:
[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
