We know that we should have base_mono = wall_to_monotonic + xtime_sec Instead it is base_mono = wall_to_monotonic + xtime_sec - seconds from boot time which is... zero. Given this is the only use of base_mono in a notifier, I wonder if it is as simple as this (which I don't have time to test right now): diff --git a/kernel/time/timekeeping.c b/kernel/time/timekeeping.c index fb4a9c2cf8d9..f6807a85b8c9 100644 --- a/kernel/time/timekeeping.c +++ b/kernel/time/timekeeping.c @@ -443,9 +443,9 @@ static void timekeeping_update(struct timekeeper *tk, unsigned int action) ntp_clear(); } update_vsyscall(tk); - update_pvclock_gtod(tk, action & TK_CLOCK_WAS_SET); tk_update_ktime_data(tk); + update_pvclock_gtod(tk, action & TK_CLOCK_WAS_SET); if (action & TK_MIRROR) memcpy(&shadow_timekeeper, &tk_core.timekeeper, :) Paolo > Well hidden and still so obvious that it's even visible through the > brown paperpag I'm wearing ... -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
