Pophawk - 1) While faslkdjfalskdjfalskdfj's post was a little suspect for being vauge that wasn't really, what I least I, would call a troll. It's just a questionable report of someone's expereince. 2) Trolls LOVE to take time to track and respond to replies, doing so IS the hallmark of a Troll and what they live for. It is why trolls make personal attacks, question semantics and generally sow discord to illicit attention. http://en.wikipedia.org/wiki/Troll_(Internet)
faslkdjfalskdjfalskdfj - Apple support is who suggested I return/replace my rMBP as well. They didn't suggest it was a 1:1000 failure (and while I beleive you, that seems a very unusual statement to come from AppleCare). They told me "you should not have any problems with your brand new Mac and should go to an Apple store and exchange it for a new one immediately". As I sadly don't have an Apple store available to me I'd asked if the exchange period could be extended a few weeks so I could do it while I was traveling in Vegas next week, which they said they could arrange, however, she added that since Id originally purchased it from MacMall the exchange in store would be for a refurbished MBP, not a brand new one. Further I should call a head to make sure the store had a refurb on hand or to have them order one for me just in case. As I didn't want a refurb if I could avoid it I ordered a new one from MacMall and sent the existing one back as a return (under 14 days) instead of an exchange.
Summarizing: The Sleep Wake Failure seems to occur in PowerNap capable macs running 10.9 with USB devices attached (hub or otherwise). If the computer is put to sleep with USB drives attached it will sponaously reboot while sleeping.
There are other reports of spontaneous reboots while running (likely kernal panics) and crashes without USB drives attached but none of those reports have provided a Sleep Wake Failure report to suggest it's related to this exact issue.
It's worth noting at the bottom of a Sleep Wake Failure report is well tell you what USB devices are attached should you be troubleshooting this yourself.
