When i move my USB-Mouse i can see the seconds pass by. (Heavy moving causes up to 2-3x higher "speed".) Then maybe the USB-Keyboard problem is related. Every now and then a key gets "stuck" and is repeated until i press another key. (Very annying when you press "CTRL-n" in Mozilla for getting a new window. Personal "record" was about 50 Windows) (Currently i'm typing with the "normal" Keyboard) But here is the wanted info Record with this from another machine: -- time.sh -- #!/bin/sh while true do echo -n "Localtime: " date echo -n "Remotetime: " ssh date \; cat /proc/interrupts sleep 5m done -- End -- -- Begin -- Localtime: Mon Aug 5 23:18:03 CEST 2002 Remotetime: Mon Aug 5 23:18:34 CEST 2002 CPU0
