(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.
