I did a diff from v5.10-rc4 to drm-tip to look for suspicious changes.
Some candidates are

    8e3784dfef8a ("drm/ast: Reload gamma LUT after changing primary
plane's color format")

Ok, that one fixes the screen colours (etc).
So 8e3784dfef8a was good and then HEAD^ was bad.

I might try to bisect the breakage.

The stack splat is entirely different.
I'll try to bisect that on Linus's tree.

The good news is I'm not getting the stack splat on rc5.
I'm not sure I can be bothered to find out when :-)

Applying 8e3784dfef8a to rc5 by hand also fixes the display colours.

I've added this commit to drm-misc-fixes and it should show up in the upstream kernel soonish.

Best regards
Thomas
