Same here, because it's random, creating a log is very difficult (I have tried). To reproduce is difficult, also. Because it's not always happening. What I see is that it happens mostly somewhere after 45minutes. When it happens the cpu is dropped from 80-90% to 10%.

Have you tried disabling FIQ FSM with either dwc_otg.fiq_fsm_mask=0x0 or dwc_otg.fiq_fsm_enable=0 to see if this is the reason for the freezes?
