Note: the hotfix now also includes an update for Windows Server 2008 R2.
130624: over the past few months I've seen this bugcheck occur with quite a few customers so I figured perhaps it would help some of you out there as well... I've also added this as a response under Online Crash Analysis. This means that after it has been reviewed and approved, the next time your machine encounters this crash, and you submit the crash information to Microsof when asked (and I hope you all do!), you will get a response in Action Center, pointing you to the relevant KB article. This means that you don't have to log cases for this issue anymore, or that you need to stroll the internet searching for a resolution... How cool is that? :)
Anyway, here is the crash information:
