[meta-freescale] Yocto Qt5 Integration for Wandboard - Kernel Panic

[Jay Cady]

Hey John,

Wow, that is really surprising.  I will give that build a try tonight and
see my results.

Do I exclude git by writing the line "DISTRO_FEATURES_remove = "git"" in my
local.conf?

If this solves it, you will be my hero.

Thanks!
Jay
