Hey folks. I have been pulling my hair out for a bit trying to figure out why the latest update is preventing my Proxmox host from achieving any C-states at all.
I am running an HA VM in Proxmox with 2 cores (OVMF BIOS and q35 machine). Everything was going fine until I updated HA today. After the updated, I rebooted the entire server and now my Proxmox host won't reach any C-States C2-C10 causing a bump in my power consumption. I am pretty sure it is HA because when I shut down HA, my Proxmox Host can reach the deeper C-States all the way up to C8. Doesn't matter how long I keep the system idle for, if HA is on, it seems like my system does not idle at all.
I am not sure why it is doing that as I have only given HA two cores.
Is anyone here running an HA VM in Proxmox? Does anyone know what may be going on with the latest update?
Here are the powertop screenshots on the proxmox host

For reference, my system is 12700k with an MSI motherboard. ASPM has been enabled in the BIOS.
Any troubleshooting steps would be highly appreciated.
