Comment:
This sounds like multiple bugs, to me; a deadlock in usb_raw should not
cause the entire OS to lock up, only the relevant applications. If you can
drop into KDL, see if you can find what all those applications get stuck
waiting on, and then who is holding it (via {{{bt}}} and then
mutex/semaphore/cvar/etc. commands.)
