New Informations: The bug is in the `bnxt_en` driver. A fix already exists (commit de37faf41ac5).
It appears that this fix is not yet included in the Ubuntu 6.8.0 kernel. The current Proxmox kernel is 6.8.12-9, based on Ubuntu 6.8.0-58.60. Would it be possible to include this commit in the next 6.8.0-based Ubuntu kernel release?
