I bisected and it turned out that commit dce5c9e35bc4085bd33eccdb8c9ec5a643507a14 "ARM: 7928/1: kconfig: select HAVE_EFFICIENT_UNALIGNED_ACCESS for CPUv6+ && MMU" is the first bad. There is nothing related in either dmesg or syslog on the device. Reverting that commit on 3.14-rc1 make those errors disappear. As my knowledge on how to deal with that stops here, advises on what to do next to find the real problem are appreciated.
