Hi Aaron,
Thanks for reporting this issue. Yinghai has already posted
a patch to fix the issue by disabling freeing of irq in case of system
shutdown. Please refer to:
https://lkml.org/lkml/2014/6/26/619
Or could you please help to try following patch, which USB free irq
when shutting down USB controller.
