On the mioa701 with a PXA272, the problem occurs as well in the lowest frequency
(104 MHz). If I block the frequency at 208MHz, no hang occurs.
The hang occured several times in the boot sequence, before rootfs was even
loaded.
This happens even with no SD card inserted, with USB gadget driver loading the
CPU, and then idling.
