I cannot guess the cause of your setrq panic; but you can prevent
the secondary panic and subsequent update failure by altering the
sleep code.  Add the "if (panicstr) {" ... "}" part:

sleep(chan, pri)
	...
	s = spl6();
	if (panicstr) {
		/*
		 * Let interrupts in for a moment, then just return.
		 * The splnet() really ought to be spl0(), but I'm
		 * too timid to do that.
		 */
		(void) splnet();
		splx(s);
		return;
	}
	if (chan == 0 || rp->p_stat != SRUN || rp->p_rlink)
		panic("sleep");
	...
