Hardware Event-Based Sampling fails to run

[Takap]

When running VTune under the following conditions, the entire OS crashes about 2 out of every 3 times.

Environment: OS: Windows 10 IoT 21H1
CPU: Intel Xeon Gold 6548N

----------

VTune Profiler:

- Version: 2025.3.0
- Type: Hotspots
- Hardware Event-Based Sampling
- CPU sampling interval: The same issue occurs at any value between 1 and 100
- Collect stacks: ON/OFF does not matter
- Launch VTune Profiler.
- Select Hotspots analysis.
- Start collection.

Before the crash occurs, the following logs may appear in the console:

vcs\collectunits1\tmu\src\tmu.c:425 write_trace: Assertion 'err.error_code == TMU_ERROR_SUCCESS' failed.
tmu425: err.error_code == TMU_ERROR_SUCCESS : BUG! : Cannot write magic record to trace, err=2 syserr=0

Event Viwer StopCode: 0xc0000409

** ---- The OS crashes at this point. ----

Is this a known issue? Are there any workarounds or additional diagnostics I can try?
If you need more information, please let me know.

Thank you.

When it crashes, are there any log files generated?

[Takap]

When the PC does not crash, I see the following logs:

In the application console, I get these outputs:

> vcs\collectunits1\tmu\src\tmu.c:425 write_trace: Assertion 'err.error_code == TMU_ERROR_SUCCESS' failed.
> tmu425: err.error_code == TMU_ERROR_SUCCESS : BUG! : Cannot write magic record to trace, err=2 syserr=0

A log file is also generated in the project directory:
C:\Users<>\Documents\VTune\Projects<>\r008hs\log\perfrun-2025.05.21-15h48m35s.1428.log

Additionally, log files are created in the temporary folder:
C:\Users<>\AppData\Local\Temp\amplxe-log-SubPOT\2025-05-21-15-48-35-103.amplxe-runss.exe
amplxe-2025.05.21-15h48m35s.1428.log

It seems that no logs are saved when the OS crashes, so these are the logs collected from cases where the crash did not occur.
Thank you.

Thanks for providing the logs, need to check.

When you run self-check utility, are there any logs generated?

[Takap]

Yes, after running the following checker program:

> C:\Program Files (x86)\Intel\oneAPI\vtune\2025.3\bin64
> vtune-self-checker.bat

the log files were output to the following location, so I am attaching them as files:

C:\Users\<<MyUserName>>\AppData\Local\Temp\vtune-tmp-<<MyUserName>>\self-checker-YYYY.MM.DD_HH.MM.SS

Just like with VTune Profiler, running this checker program sometimes causes the PC to crash. Sometimes it completes normally, and other times it results in a crash.

I am uploading both types of logs:

1) log(Completed normally).txt
2) log(PC Crashed).txt

Thank you.

[yuzhang3_intel]

Please attach the whole folder. In addition to the crash log, some other log files are recorded in the folder.
