I made this test four times and the results  were the same: linux
freezes and becomes unresponsive. Only solution is to reset the box. I
do not know if the problem is with the USB devices sub-subsystem or a
possible ext4 race condition.

Can you use alt-sysrq to get some stack traces or a register dump out,
so we can see where the kernel is hanging?
