Re: libinput bug: timer offset negative

Please search before posting: https://bbs.archlinux.org/viewtopic.php?id=222671
Also: https://bugs.freedesktop.org/show_bug.cgi?id=96312 - the "error" is (probably) a symptom of the stalled system. You need to figure what stalls the system, the libinput message will (very most likely) go away with that problem.
