Comment 18 for bug 1921468

FYI I'm working on the autopkgtest issues - but all of those are known flaky cases, so I expect no long term blocker.

The other two bugs that are part of this SRU are verified by now, so it needs just this one to complete - which we know can be hard to re-create without special unlucky bootloader record sizes.

On the good side, I've not seen regressions to the non-affected-boots

@Marc - let us know once you've completed the testing
