I've got the 'splat' below during boot. This is an 8-core C2758 Atom cpu using the on-board/cpu graphics. User space is Ubuntu 20.04.
Additionally the X display has all the colours and alignment slightly messed up. 5.9.0 was ok. I'm just guessing the two issues are related.
Sounds likely. But it would be lovely if you could bisect when exactly the problem(s) started to both verify that, and just to pinpoint the exact change..
I'm working on it - have been all afternoon. (I'm on holiday and it is raining...)
5.10-rc1 fails, so it is something in the merge window. I suspect I'll just hit the pull of the drm changes. The bisect suddenly build a 5.9-rc5+ kernel! So I'm retesting a good/bad pair with likely dates and will restart it.
Annoyingly the test system defaults to booting the highest version kernel - not the one I've just build; I may have given it a wrong answer. The builds also all take 20 minutes; so the bisect is slow.
