Partial wake from sleep
I have been trying to sleep/wake my Early 2009 MacPro without success. Sometimes it wakes completely; other times it comes up with the clock advancing but with no keyboard responsiveness. The only way to get thing working is a power reset which is a major pain. Been through the PRAM SMC reset loop.
In looking at the kernel log, I see all kinds of activity after the Mac is in sleep mode, both when it returns properly and when it does not. I have a power meter on the UPS feeding the Mac Pro and some other components. When the Mac first goes to sleep, the power drops to around 75 VA (volt-ampers, similar to watts except with power factor included). From this condition (deep sleep?), I must power cycle to get responsiveness. Some times it reports around 170 VA (light sleep? - the power led still indicates sleeping), and it does return successfully from sleep with full responsiveness.
The only USB connections are the 27" LED monitor and the keyboard. Other peripherals are plugged in to the monitor.
Given my usage patterns, I'd like to take advantage of the power savings sleep affords but have been unable to do so.
Any ideas or thoughts on how to resolve this issue?
