[RESOLVED] Win2008R2 RTM/SP1: STOP 0xD1 in storvsc!StorChannelVmbusCallback+0x2b5

Status: Resolved

Update 120111: The update is now available from Download Center: https://www.microsoft.com/download/en/details.aspx?id=28651.

Update 111102: The private has been approved, and we are working on the public hotfix now. Issue resolved, moving onto the next. ;) Special thanks to Didier for the effort and cooperation!

Update 111027: Privates for this issue are ready, and I am shipping these to some customers for testing now.

Update 111025: Great news! We have root-caused the problem and a hotfix is in the works. This is planned currently for December release (HTP11-12) under KB2636573.

Update 111021: Another customer mailed me with this problem. Slowly but surely we are making progress with this issue. Keep watching this space!

Update 110930: The instrumentation did not have the desired result yet. We are working hard to get in a reproduction setup in-house. Development is looking at dumps provided after installing the instrumentation.

Update 110912: Two customers are running the instrumentation now... fingers crossed! :)

Update 110905: We've created new instrumentation that I have sent to my customer. I expect various other customers to follow. As soon as we have results I'll update here.

Update 081128: Things went silent on this... until now! Additional customers have contacted me on this. We currently have instrumentation for this to further diagnose the problem. If you have a (fairly) solid reproduction of this, and you are willing to help us out by running the instrumentation, please create a case with us and send me the resulting SR#. More info on this will follow shortly!

We are currently working on an issue where we see a STOP 0xD1 on virtual machines on Hyper-V, with this stack:
