I just set up a new Dual 1 Ghz Powermac yesterday, and have a had a few problems. The biggest one, is that whenever I put the computer to sleep, and do not wake it up for a long period of time (once overnight and a few times for about and hour), it comes back on with a kernel attack. It makes me restart by holding down the power button. I would like to be able to successfully put it to sleep instead of shutting down every time. My 450 Mhz AGP Graphics Powermac goes to sleep fine, but my new one doesnt. Has anyone else experienced this problem or have a solution?
