This is strange because last week I booted myself a BBB.
This actually looks like the serial doesn't output, perhaps the kernel
does boot. I wonder if console is right for the kernel cmdline.
On Friday I built and booted from
master:db80f796e78746014a0f9497638e5c6fd2953ef0 which is a bit earlier
that what you have but basically the same thing (updates for kernel
which should fix things, I've tested with SRCREV_meta_pn-linux-yocto =
"${AUTOREV}" those before they entered in master because I didn't had
HDMI output on my master commit).

I'm gonna rebuild from daisy tip and see what happens.

Cheers,
Stefan
