It tends to do that, especially on slow drives (ie anything but nvme), depending on the io scheduler used. I have seen it with "cfq", but not with "none". iostat would probably show you 90+ % iowait when it happens. That by itself does not indicate the error we are trying to track down here. -- You are receiving this mail because: You are watching the assignee of the bug.
