I tried 3.10 on the master branch. I get the following messages during my
build:
# change from 3.0.35 to 3.10 by adding the following line to my local.config
PREFERRED_VERSION_linux-imx_mx6 = "3.10"
build$ bitbake core-image-minimal

Am I doing something wrong or just trying to use 3.10 before it's been
integrated into master?

Doug,
I think you might be seeing issues with the new toolchain 4.8. There were
some ARM errata workarounds in defconfig in 3.10 to fix issues with new gcc
toolchain. Also the new eglibc has performance issues we are patching in
our beta release.
Try building on 4.7 toolchain which was I believe the same one that 3.5.7
was tested against.
Best to switch to 3.10 as that will go GA not 3.5.7 which was stopped to
move to an LTS kernel. I think 3.10.9 is almost ready to be fully
upstreamed into dora branch. So until it is merged, use the master branch.

Subject: [meta-freescale] Kernel 3.5.7 hangs
I am trying to build kernel 3.5.7 Yocto 'Dora' using imx6qsabresd.
Everything builds without an error and I get a new uImage, as shown below.
However, the kernel hangs while starting up. Some folks in the imx
community have tried using CONFIG_EARLY_PRINTK=y, but there are no messages
printed by kernel.
# I first clean before changing versions in order to clean up the 3.0.35
files...
bitbake -c cleansstate linux-imx
# change from 3.0.35 to 3.5.7 by adding the following line to my
local.config
PREFERRED_VERSION_linux-imx_mx6 = "3.5.7"
# rebuild kernel
bitbake linux-imx
# rebuild image
bitbake core-image-minimal
