Dual Quad-core Mac Pro reboots from sleep
I have an IOGear firewire hub plugged in with nothing attached to it and lots of USB devices plugged in.

I have posted earlier in this thread some of my experiences on the issue of the Mac Pro rebooting from sleep. I completely erased and zeroed my internal HD. I reinstalled OS 10.5.1 and all updates directly from the installation disk shipped with the PC. Even before installing any software other than the OS, my Mac Pro Early 2008 machine underwent a reboot when awakened form sleep mode. I do not have Bluetooth turned on. I feel these observations rule out the value of reinstalling the OS and software and that Bluetooth has nothing to do with the problem.
I have also had my Mac Pro fail to either awaken or reboot from sleep (twice over a three week period) requiring a forced reboot using the power button.
I do not know whether this is a firmware or a Leopard OS problem on the Early 2008 Mac Pros. If I had to guess, I would guess that the driver for the video card (ATI HD 2600) are involved, but that is nothing but a guess on my part.
This problem is irritating in the top end Mac and I have sent Apple some strong feedback to the effect that the problem needs to be solved soon. I have not heard from a single Early 2008 Mac Pro owner who has NOT experienced this problem at least once. I would urge others to send feedback to Apple.
