Wakeup problems after Mavericks Upgrade - forced reboots

[Hevelius]

Since upgrading to Mavericks I am getting hangs of the Wakeup From Sleep function on my 2013 MBA.
The screen stays blacked out and the only way out is a hard reset (power off).

It doesn't happen every time the MBA goes to sleep but has happened 4 times in the last 36 hours since I upgraded. It has happened on both battery power and A/C.
I had ML for 2 months since purchasing the MBA in August and had absolutely zero issues with it... it's only since the Mavericks upgrade that this problem appeared.

Anyone else had similar problems?

Not really sure what to do. I'm tempted to do a clean install, but really reluctant to go through all that work if its not going to fix it.
