Interesting indeed. I have no idea what's so special about Fedora host - this 
is the first time I hear about issues with it. I may try experimenting with 
different VMs once I have more time...

Same here - building for different targets with different kernels from meta-ti 
and on 32 and 64 bit hosts and never had an issue like that...

This is not a "Yocto" kernel, this is a vanilla mainline 3.14 kernel (as a 
successor to 3.12 work done in meta-ti). Indeed, cape support is missing, as 
it is still not merged upstream, going through numerous iterations... The 
point of meta-beagleboard was to work on cape support and such, with the goal 
to upstream it, while meta-ti kept on working on SoC and peripheral support. 
Due to different circumstances, meta-beagleboard still uses 3.8 kernel. Once 
it is accepted upstream, it will be part of the mainline kernel and one of the 
later versions of the Yocto Project reference BSP.
