I tracked it down in update_process_times, where we have the following: #ifndef CONFIG_PREEMPT_RT run_posix_cpu_timers(p); #endif Yea, that would do it. :) Hmm.. Looking through the archives, I came up w/ the discussion here: http://www.uwsg.iu.edu/hypermail/linux/kernel/0509.3/1579.html I was just curious what folks are thinking about for a fix here? Should we just create a soft timer that calls run_posix_cpu_timers? thanks -john - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
