I've been attempting to test this locally on hardware and in a
virtualized environment (Hyper-V to be precise), and I can't reproduce
the failure case. This makes it hard to test that my fix works.

So, what I can tell is that while we can also change the grub config
itself, it looks like 'text' is not being properly skipped in the EFI
case, where it's already known not to be supported. I have an untested
(see above) patch to fix that.

Could you please attach a grub.cfg that is affected, and tell more about
the system on which this is happening?

It looks to me like just forcing 'set gfxpayload=text' does not cause
the warning message to appear (or it shows up and quickly disappears,
too quickly to be noticeable). I have also tried setting console=ttyS2
(some other device I knew would not be connected) to avoid text being
obliterated by kernel messages, but it still does not exhibit the
failure behavior.
