This one is definitely a new regression. Hopefully the AT91 maintainers
(now Cc'd) can have a closer look.


6b1d7b6f54c7 would be a candidate for a culprit.

Conflicting Boot Failure Detected: (These likely are not failures as other labs are reporting PASS. Needs review.)

@Alexandre: Because it's passing in my lab and failing in yours, I'm
guessing this is still the UART overflow issue we've discussed before?

What's strange is that this defconfig in your lab seems to only be
booting for stable/linux-4.4.y[1] but not mailine or newer stable trees,
so I couldn't check if the problem still exists in mainline.
