[Łukasz Zemczak]

Hello Paul, or anyone else affected,

Accepted u-boot into focal-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/u-boot/2020.10+dfsg-
1ubuntu0~20.04.2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)

Bug description:
  I first noticed this on a focal daily image (http://cdimage.ubuntu.com
  /ubuntu-server/focal/daily-preinstalled/20201202/ or the current
  pending one should be able to reproduce it). On the rpi400 device, it
  goes into a reboot loop. I'm also seeing this behavior with the
  current uc20 arm64 images on rpi400, and I suspect the same problem
  could be happening on cm4, but I can't confirm that yet because I
  don't have one in front of me.

  Here's the output I'm getting from serial before it goes into the reboot loop (it gives this output each time it reboots):
