BSOD on Windows 7 using Amplifier 2015 Update 1

[AndrewC]

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?

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?

Here is complete analysis of VTune BugCheck 0x101.

@Peter

Do you have any info regarding BugCheck 0x101?

[Peter_W_Intel]

@iliyapolak

Thank you for data, but it is under investigating. I will update news if any process.

[Bernard]

Thanks for updating.

[Peter_W_Intel]

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.

[AndrewC]

Things are working for me just fine now!
