From: Eric Valette

I have the following systematic crash at boot since 5.10.20 (.19 was ok)

This laptop has two graphic cards:

03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 14 [Radeon RX 5500/5500M / Pro 5500M] (rev c1)
07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir (rev c6)

NB: cc me I'm not subscribed
