Garbled display with kernels 5.15 and 5.14
#3
I started with kernel 5.14.12 to find the version that breaks with my current configuration. The result was a kernel that worked (i.e. display was not garbled) roughly 50 % of the time. That was quite frustrating so I abandoned my plan to find the "breaking" version.

Instead I decided to try again with kernel 5.15 and start from its defconfig instead of a Debian kernel config (which I did previously). Some iterations later I have arrived at 11 CONFIGs that I need to change to get "everything" working with my Debian installation.

Display has so far not shown any issues, neither on cold boot nor on reboot.

I have no idea which part of the previous kernel configurations were responsible for the display issues. A bit disappointing but I probably will not investigate this further.
