Are you sure that video0 is the very same device you're seeing in the boot with the self-built 5.10 kernel? -- You are receiving this mail because: You are the assignee for the bug.

It's all my fault. :) I'm using the loopback video device and only recently I configured the system to load the module on boot. That resulted in renumbering of the available video devices, where the loopback is now the first (video0), and not the last (video4) as it used to be. Apologies for the noise and thanks for your help! -- You are receiving this mail because: You are the assignee for the bug.
