Apologies, I couldn't find the time to respond or reproduce the issue
lately. I've looked into the Windbg output, but without a full stack
trace it's difficult to know what's going on.

To enhance the debug info, you will want to build your own drivers and
load the resulting symbols in Windbg. Each driver repo from xenbits
contains a `build.ps1` file that could be run from within the VS
developer shell. You can use `-type free` for a release build or
(preferably) `-type checked` for a debug build. You'll have to bring
your VM into test mode to load your own build.

Once you have attached your VM to Windbg, you could run the command
`!analyze -v` to get a full report.

Feel free to reply if you need help with building the drivers or
debugging the VM.

I hope that helps.

Best regards,
