While running vtune-self-checker.sh script, Kernel is getting panic

Hi Team

I'm running version 2023.1.0 of VTune. We are getting the below error while running the vtune-self-checker.sh script

Hi,

Thank you for posting in Intel Communities.

We were able to run the self-checker (vtune2023.2) from our side without any issue (Since there is no integrated gpu in our machine, gpu analysis failed). Attaching a screenshot for your reference.

We can see you are using an older version of Vtune could you please upgrade to the latest version?

If you still face issues with the latest version of vtune please follow the below steps:

Building the driver using the below command:

sudo <oneapi_install_directory>/vtune/latest/sepdk/src/build-driver

(eg:/opt/intel/oneapi/vtune/latest/sepdk/src/build-driver)

The driver build will be successful. Once this is done, load the drivers by running the following commands:

sudo <oneapi_install_directory>/vtune/latest/sepdk/src/insmod-sep -r

You can check the status of the loaded drivers using the below command:

sudo <oneapi_install_directory>/vtune/latest/sepdk/src/insmod-sep -q

After running the above steps, please rerun the self-checker log once again and let us know.

If this resolves your issue, make sure to accept this as a solution. This would help others with similar issue. Thank you!

Thanks,

Jaideep

After upgrading the VTUNE Version to latest, Kernel Panic is not seen on the system while running self checker script.
