In order to avoid kernel switching at the end of the release cycle, the plan is to do the meta-intel BSP development on the linux-yocto-dev kernel. All the BSPs will be using the dev kernel for regular testing. The fixed known srcrevs will be used for the dev kernel recipes. But the kernel team would be using autorevs for their internal testing, and update the kernel recipe srcrevs accordingly. Important thing to note here is, this process can bring out lot of kernel bugs, which is a nice thing, as it will avoid kernel issues late in the release cycle.
This is mostly done. Just waiting for Beth to make the switch in the poky MUT branch or AB setup. Nitin is using the dev kernel for his weekly validation.
we have moved to v3.14 kernels now.
