The kernel version 5.16.8-1-default has the option CONFIG_SYSFB_SIMPLEFB=y in the config. On my computer this leads to a black screen and no contact. I have to shut down hard to recover. The journal is showing no information about what happened.

The kernel 5.16.4-1-default did work fine. There are some changes in the .config between the two versions kernel. Compiling the 5.16.8 kernel with ' #CONFIG_SYSFB_SIMPLEFB not set' boots the system normally.

The full diff between the Thumbleweed kernel and the one compiled by me is below. The 5.16.8-seppe- kernel is working fine and does not have the 'CONFIG_SYSFB_SIMPLEFB=y'.
