I can't help but think the hang here is related, particularly to the subtle timing issues that are plaguing the 4 vs 8 bit detection. Seems like there's just something not right in the eMMC detection/startup?

I'm in the same boat. However, Ian is in the process of backporting the CURRENT arm updates to STABLE. If I can get 1GHZ working with 10-STABLE, then I'll be very happy. WITNESS is an easy one, create a config like this: ident MYCONF include BEAGLEBONE nooptions WITNESS And build with it (set KERNCONF if you're using crotchet-freebsd) and you'll get a WITNESS-free kernel.
