Did you try the patch that Damien posted here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1006149#131 Asking as you posted a different patch later in your reply. I _think_ that Damien's patch is supposed to supply more information, not fix the issue. I'm not sure whether the patch should be applied to the working 5.15 kernel or the non-working 5.16 kernel though. In the former case a full dmesg output of a boot without the patch and one with the patch should be attached to this bug report. In the latter case there likely won't be a log file and in that case a video of the (5.16) boot without and with the patch should hopefully give us more information. Damien: can you clarify whether the patch should be applied to the 5.15 or 5.16 kernel?
