My 2651XM's CPU reaches % 100 and becomes unstable. Once i reload, it becomes OK, but CPU usage starts increasing slowly % 27-% 28-....% 61-% 62-...% 91-% 92...boom. Reload and the same thing occurs. When I show processes cpu sorted, IP Input takes the lead. But interesting enough (Maybe i dont know how to interpret "show cpu process sorted") lets say that it says last 5 second usage % 60 in first line, then shows each processes last 5 second usage like IP Input % 23 process x %z and so on in following lines. When I add all processes' last 5 second usage, the sum is NOT equal to the total stated in first line. Something incrementally using my CPU and not freeing up, and i cant see it.
