Reproduced this lock-up (status LEDs stop blinking when console output stops) on current linux-linaro tree (v3.12-rc4 based, the tag is ll-20131015.0).
Disabling CPU_IDLE makes the 4460 board to boot to the command prompt. (Panda 4430 boots fine regardless of CONFIG_CPU_IDLE setting)
Amit (Kucheria), could you comment on that? Would disabling CONFIG_CPU_IDLE be a valid workaround for the 13.10 release, or an overkill?
Thanks!
