Mac Pro crash on sleep
I've got a 2008 Mac Pro (MacPro3,1) running 10.6.4 that crashes when I put it to sleep. It started a couple of weeks ago, prior to that, all worked perfectly.
The pattern is this: tell it to sleep (by front button, keyboard or menu item)
Makes usual preparing for sleep noises
Monitors go black, go onto standby
Sleep LED starts pulsing, but *the fans stay running*.
The usual click of the power relay never happens.
From this state, it won't wake up. All I can do is hold the power button in to power it off.
Normal shutdowns and reboots work fine; it's just sleep that's a problem.
I've read of other Mac Pro sleep problems, but they seem different - crash on wake, reboot on wake etc, and I'm not seeing those problems.
Any idea why this might be happening and how to fix it?
