I am getting a 100% repeatable BSOD on Windows 7 running Amplifier 2015 Update 1 (build 380310), native code.
Advanced Hotspots ->Hotspots -> NO PROBLEM
Advanced Hotspots ->Hotspots , stacks and context switches ->BSOD after a few seconds.
Suggestions?

@vasci_
Would you please run a sort of reversed experiment: enable call stacks, but disable context switches?
We need to see the picture from different angles. Thanks!

I suppose that this piece of x64 assembly code could be a culprit of the BugCheck 0x101. It seems like some kind of spin-wait loop on variable which is executed by the machine code shown below. This is CPU #7 which is running Solver.exe process threads.Thread fffffa8024f41060 is in running state with RIP pointing to vtss+0x11691 (fffff882`1065d691 4885c0 test rax,rax) instruction which is performing spin-wait loop. Could this be a cuse of CPU6 hang?

See similar issue in this thread to get fixed vtss.sys and know *steps*, in last page.
Let me know if you still have this problem after upgrading to 2016 U2 with fixed vtss.sys. Thank you.
