This issue couldn't be reproduced during the test.
However, for TI Panda 4460 with the same image, an "Internal error" occurred and hung the board, but looks like it's related to the wlan driver, not the problem described in this bug. Anyway, console log output attached, if necessary, I will append the log to Bug 1164329 as well.
For the TI Panda 4430 with Linux Linaro ubuntu image:
