The thread is in the state TDS_CAN_RUN so it's runnable but not on a run queue
or running. The only way that I know that this can happen is if priority
propagation happens after the system has already panic'd in which case you
are about to deadlock anyhow since you are blocking on a lock owned by a
thread that will never get to run again. You can try adjusting
propagate_priority() to treat TD_CAN_RUN(td) the same as TD_IS_RUNNING(td)
and maybe you will get your original panic message.
