After too many system crashes coming out of SLEEP S3 mode, I sent a bunch of minidumps to Microsoft and the reply was as follows:
Thanks for uploading the dump files - they were invaluable. Both of them appear to point to inspect.sys, which according to a cursory internet search, is part of Comodo Firewall. It appears you are not alone in this issue:

So, I checked all of the drivers on my system and am up to date on everything. I'm happy to provide the dumps to the folks at Comodo for debugging purposes. Just advise where to send them.
Of course the problem isn't a hard one in that my laptop doesn't crash every time it comes out of S3, only when I'm in a hurry to get back on my system
