My G4 Powerbook running 10.4.5 has started to freeze (for about 1-3 seconds) at regular time intervals. Looking in the system log using Console, I get the following error message: Mar 25 09:57:36 grue kernel: AMS::infiniteIntTimerEventHandler ERROR have infinite interrupts, disabling I get these messages every 5 minute. I have tried shuting down and restarting, but the problem persists. Any ideas? How do I trace which process resulted in the error?
