Hi Salvatore, Thank you for the guidance.
At the moment, I am unable to test on a clean Debian kernel. However, I thought Proxmox was built on the Debian kernel, but I’m happy to report this issue upstream as you suggested. I will keep this report updated with any findings from my tests or responses from the upstream maintainers. Thank you very much.
