To workaround the issue, please follow anyone of the following:
Disable CC6 without a system hardware reset by running the attached Python script in the ESXi shell. Disabling CC6 is not persistent, so the user will need to run the script again after each full reset.
Alternatively, the machine may provide a way to persistently disable CC6 as a BIOS setup option. Details on how to do this depend on the hardware vendor and cannot be provided in this article.
