It shows up early before you do an !analyze -v, and the result is a strange prompt and the data ends up being missing or odd. The error is as followed: Code: The context is partially valid. Only x86 user-mode context is available. The wow64exts extension must be loaded to access 32-bit state. .load wow64exts will do this if you haven't loaded it already. If you see this, that means you came across a bug in Windows 7/2008 R2 that bugs out the processor context that's saved when generating the crashdump. This only seems to occur on processors that have particular special features enabled on it. The solution is to have the individual sending the crashdumps to download the hotfix here. Then after installation they'll have to have new crashdumps generated.
