I ran into a similar issue on STM32F4 recently - hanging there, or: Unhandled exception: IPSR =3D 00000006 LR =3D fffffff1 CPU: 0 PID: 1 Comm: swapper Not tainted 3.18.0-rc5-00003-g489983a-dirty= #25 task: 90432000 ti: 90434000 task.ti: 90434000 Unhandled exception: IPSR =3D 00000003 LR =3D fffffff1 CPU: 0 PID: 1 Comm: swapper Not tainted 3.18.0-rc5-00003-g489983a-dirty= #25 task: 90432000 ti: 90434000 task.ti: 90434000 -Boot 2010.03-00003-g934021a-dirty (Nov 26 2014 - 06:52:49) My debugging indicated that %pF was not working, used among others in checking for blacklisted initcalls. Disabling CONFIG_KALLSYMS worked around this, so I assume something there is not compatible with XIP...
