I'm not sure why a Host Controller would die and (hopefully) clean up properly, but that needs investigation. Looking at the oops probably won't yield useful results in terms of finding cx231xx bugs as it happens after the first host controller has bombed out. You should consider having /boot/System.map and the real klogd installed on your system, so the oops backtrace has meaningful symbol names as opposed to addresses (which are meaningless to anyone without a copy of your built kernel).
