[MinnowBoard] NVRAM Issue: No Video, but UEFI not bricked

[John Roach]

Hello all. I'd like to revive this as it has been a problem this last
week.  One day I had to re-flash my boards 3 or 4 times until I got a
working setup.  Now when I turn off the MinnowBoard and turn them back
on I get nothing until the Ubuntu loading screen.  Similar to what
Hans was talking about above.  I also ran into the same symptoms as
described in this comment
(https://bugzilla.yoctoproject.org/show_bug.cgi?id=7027#c8).  Seems
bug 7027 hasn't had any more activity on it, does anybody know how
widespread this issue is or if a fix is planned?
Cheers,
