--- Comment #1 from Ilia Mirkin <[email protected]> --- nouveau_fan_update: spin_lock_irqsave(&fan->lock, flags); /* schedule next fan update, if not at target speed already */ if (list_empty(&fan->alarm.head) && target != duty) { u16 bump_period = fan->bios.bump_period; u16 slow_down_period = fan->bios.slow_down_period; ... ptimer->alarm(ptimer, delay * 1000 * 1000, &fan->alarm); If delay is somehow 0, the ->alarm will cause nouveau_fan_update to get called immediately. Can you add a printk to that function that shows the values? (This may end up totally flooding your dmesg too... but I think the values may be the same across prints.) e.g. diff --git a/drivers/gpu/drm/nouveau/core/subdev/therm/fan.c b/drivers/gpu/drm/nouveau/core/subdev/therm/fan.c index c728380..9453afd 100644 --- a/drivers/gpu/drm/nouveau/core/subdev/therm/fan.c +++ b/drivers/gpu/drm/nouveau/core/subdev/therm/fan.c @@ -88,7 +88,7 @@ nouveau_fan_update(struct nouveau_fan *fan, bool immediate, int target) delay = min(bump_period, slow_down_period) ; else delay = bump_period; - + nv_info(therm, "Scheduling fan update in %d (slow: %d, bump: %d)\n", delay, slow_down_period, bump_period); ptimer->alarm(ptimer, delay * 1000 * 1000, &fan->alarm); } -- You are receiving this mail because: You are the assignee for the bug.
