Running Proxmox 8.4 on my main workstation, with a Windows 11 VM and GPU/NVME passthrough. The last kernel update (6.8.12-15-pve -> 6.8.12-16-pve) borked my Windows 11 VM, so I pinned 6.8.12-15-pve to resolve. Thinking it's probably time I upgrade to version 9. Will my pinned kernel cause me any problems during the standard upgrade procedure? (pve8to9 --full didn't report any problems)

Figured I'd take the time to dump some detail on why the VM borked under the 6.8.12-16-pve kernel. (Seems like it was the SATA controller I use to passthrough a bluray optical drive.)

Code: 
journalctl --since "2025-11-26 09:48:05" --until "2025-11-26 09:48:08" --no-pager
