I don't yet know what is going on, but building in the same directory with sources (B = S) makes it work regarless of the path length: /OE/RAM/poky-111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111/22222222222222222222222222222222222222222222222222222222222222222222/3333333333333333333333333333333333333333333333333333/tmp/work/beaglebone-poky-linux-gnueabi/linux-yocto/3.14+gitAUTOINC+928d7b2dda_0143c6ebb4-r0/linux So, I just commented out setting kernel-specific B in linux-yocto.inc and any kernel now boots with long path: #B = "${WORKDIR}/linux-${PACKAGE_ARCH}-${LINUX_KERNEL_TYPE}-build" I'm copying Richard and Bruce directly to see if they may have a quick insight and/or accept it as a workaround for the release. I'll keep digging further, but if anyone cares to verify the above workaround works for them, I would appreciate. Thanks! -- Denys
