Hi all,
I am finding our arm64 D05 board particularly slow to boot from
linux-next, specifically a 30+ second pause when setting up CPU features.
I tried to bisect, but I am finding bisect holes (board does not boot at
all).
Snippet good, like v4.20-rc6:

Anyone else notice a similar issue?
Our nextgen D06 board does not seem to have this issue.
Thanks,
