Late 2013 Mac Pro wake from sleep crashes - which logs to look at?

Question

I started encountering wake-from-sleep crashes with my late 2013 Mac Pro a couple of weeks ago.  Prior to that the system had been pretty solid.  Other than app and OS updates installed from the App Store, I can't think of any software changes that might be responsible.
What logs should I be looking for that could be helpful in diagnosing the problem?  Looking at other posts where people have been trying to diagnose similar issues I see people posting portions of panic logs that show which modules were loaded and might help point to a culprit, but I can't seem to find a log with a panic message in it.
I had thought I'd determined my Anker USB3 powered-hub was related to the crashes, as when I disconnected it from my system I went several days without a crash.  Today I reconnected the hub with just a few devices on it and got a crash. I disconnected the devices but left the hub attached but got another crash.  I then disconnected the hub again, assuming I'd proved it was the culprit, but the machine has now crashed twice without the hub attached.
I'm running OS 10.9.4.  Looking at other reports people reported some specific programs that added kernel extensions that were suspected to be the problem, but I don't have any of those programs installed on my Mac. The problem doesn't happen every time I wake the machine, but has happened at least four times today alone (after about three days of no crashes.)

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
