Xorg crashed with SIGSEGV when using the RADEON driver - please help with Launchpad Bug #1970473

Please confirm and try to solve:

Cannot use vertical monitor with AMD hardware on Xorg

This is an upstream issue, reported against Ubuntu 22.04, that probably effects all distros.

Yes, if you know some devs who can fix this upstream please tell them

I reproduce the bug on these:

  1. Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM]
