No. I only see when screen is blanking a cpu totally busy. There is a command to investigate ant I have seen that cpu stalled due to an interrupt flood.
But more than once I notice the laptop freeze. Actually.. starve, for a little there is disk activity, the mouse may update once after a couple of minutes and then freeze totoally, not even the power button or a remote shell are active. The Network card continues to blink though. Perhaps this happens due to interrupt flood?
Maybe. In my case, it remains seven other CPU's... Regards, JKB
