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.
