erratic wakeup from sleep after 10.9.2 - 2012 Mac Pro

I completed the most recent OS X upgrade yesterday on my 2012 Mac Pro and now "wake from sleep" seems to work erratically (much more often not waking up and requiring a reboot). Occasionally a quick push of the front panel power button will produce results. Nothing else has been changed on the computer so I can only believe that this upgrade has been the cause.

Anyone else having this problem? Suggestions or things to reset/check?

I believe I am having a similiar issue. 3 times now since the 10.9.2 upgrade I get the spinning beach ball after a sleep/wake cycle...at login screen so can't check activity monitor or force quit the app. The only cure so far is to hold power button until it resets. I have the correct levels of EFI and SMC per earlier suggestion.

I have just repaired all permissions with disk utility...fingers crossed.

Every SSD User including OWC Users should be using TRIM Enabler or similar:

If you are connecting via WiFi,

Adjusting these two settings can help network re-connection:

1) Remove unwanted networks from the list of "known" networks under

System preferences > WiFi/Airport > (Advanced) > | Airport/WiFi pane ...

--------

2) System preferences > WiFi/Airport ...

... check [√] Ask to join new networks

"Known networks will be joined automatically.

If no known networks are available, you will

be asked before joining a new network."

Exatctly what I have. But I was sober enough not to reinstall the OS, hoping to find a sysadmin trick, no luck yet.

The "put hard disk to sleep" setting was my issue; removing the checkmark fixed this for me.
