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.)
