<pre>I tried install this driver for RX 550
(<a href="https://drivers.amd.com/drivers/linux/amdgpu-pro-18.50-756341-ubuntu-18.04.tar.xz">https://drivers.amd.com/drivers/linux/amdgpu-pro-18.50-756341-ubuntu-18.04.tar.xz</a>)
3 times and after installation the system doesn't begin, it just hold on a
black screen saying:
[ 8.6668039] ccp 0000:08:00:02: sev command 0x4 timed out, disabling PSP
[ 8.6668075] ccp 0000:08:00:02: SEV: failed to get status. Error: 0x0
In that screen system doesn't answer any command.
If I change to tty2 (ctrl+alt+f2) I could login on the terminal e do
amdgpu-uninstall and reboot (it works one time) and system would start
normally.
So I couldn't fix that I had to reinstall the hole system (Kubuntu).
