panic in ehci_abort_xfer

By unplugging a certain usb device I can reproducibly hit the panic for 
intr_context in this function. Is there supposed to be something that ensures 
we 
can never call ehci_abort_xfer on a thread that preempts the soft interrupt? Is 
the soft interrupt not supposed to be pre-emptible by the usb_task_thread? I'm 
running on an embedded MIPS platform.
