We are supporting 2 kernels for each release. One is the latest release kernel, and second is the latest LTSI kernel. The plan is to build all the LSB images with the LTSI kernel. And rest of the images will be built with the release kernel. Both the autobuilder, the one used for oecore/poky release and the other used for meta-intel release, need to be tweaked so that LSB images get built with the latest LTSI kernel. And as the LTSI kernel version may change every release, this need to be tweaked every time a new LTSI kernel is introduced. With the current LTSI v3.10 kernel, there needs to be some AB work to configure the PREFERRED_VERSION_linux-yocto = "3.10%" for the LSB images.
As per Richard the kernel version selection for LSB images should be done in the poky-lsb. This is too late for 1.7 so it will be a task for 1.8 poky release.
