OK, that corresponds to my calculation.

Strange, with my patch lr is at rt_mutex_unlock in the oops, before it
was at clockevents_program_event.  I don't understand that.
Can you try changing the pr_info to pr_emerg?
If that doesn't help, do you have CONFIG_DEBUG_LL available?  If so can
you change the pr_info (now pr_emerg) to something like:

	void printch(char);
	void printhex8(unsigned);
	void printascii(const char *);
	printascii("**************");
	printhex8(dev->shift);
	printch(':');
	printhex8(dev->mult);
	printch(':');
	printhex8(dev->min_delta_ns);
	printch('\n');

and enable CONFIG_DEBUG_LL of course?

jstultz, tglx: there shouldn't be anything that fiddles around with
shift, mult and min_delta, should it?  (Well, increasing min_delta is
OK.)

Best regards
Uwe
