check") may have helped here.
Looks like that one should be in 5.1.15+ or 5.2+. What's the most recent
kernel people have tried here?

The log was cut off so couldn't see that PSR was in fact disabled. You
can fix that by passing eg. log_buf_len=2M to the kernel cmdline.
Anyways, after a second glance at the logs I
Hmm, yes 4.32 is what the BIOS uses, so this might even help:

force-rebooting the PC now and seeing if I'll regain the image on my screen.
