Hi,
my test box won't boot 5.8-rc1 all the way but stops at
...
fb0: switching to nouveaufb from EFI VGA
<-- EOF
I've bisected it to the commit in $Subject, see below. Unfortunately, it
doesn't revert cleanly so I can't really do the final test of reverting
it ontop of 5.8-rc1 to confirm that this one is really causing it.
Any ideas?

Hi Boris,
There was a fixup to that patch that you'll also have to revert first
-- 7dbbdd37f2ae7dd4175ba3f86f4335c463b18403. I guess there's some
subtle difference between the old open-coded logic and the helper,
they were supposed to be identical.
Cheers,

Thanks, that's a good point. I reverted both but it still hangs. So
either my bisection is wrong or reverting those two is not enough due to
other changes.
I'll redo the bisection tomorrow, on a fresh head, to check.
Thx.

Ok, just did it again, similar bisection log, points at the same commit.
The commit before it:
fb172f5fe880 ("drm/nouveau/gr/gk20a: move MODULE_FIRMWARE firmware definitions")
boots ok but
2dd4d163cd9c ("drm/nouveau: remove open-coded version of remove_conflicting_pci_framebuffers()")
doesn't.
Ideas?
