It continues to fail here.
Okay, sod it, I'm at the point of just not giving a damn about whether
OMAP3 and OMAP4 boot anymore.
I'm taking all OMAP platforms out of my boot farm. I'm totally fed up
with this kind of regression happening. It's probably some config option
that someone's recently introduced which defaults to being off, thereby
breaking the ability for people to move forward without constantly having
to re-configure. This is not acceptable.
STOP BREAKING THE KERNEL.

according to speedtest.net.
