[Help] Unknown kernel command line parameters

[LoveisKind]

Proxmox keeps getting stuck on reboot but it boots up just fine when it's a cold boot (switch off power supply and let it boot up), I read up on other users having the same issues, and inserted

processor.max_cstate=0

intel_idel.max_cstate=0

panic=10

to stop it from getting stuck at reboot.
But now I am getting this warning -

Unknown kernel command line parameters

, what have I done wrong?

Note - I am on the latest version of Proxmox.

This warning about the Unknown kernel command line parameter BOOT_IMAGE can be ignored, as the message states, it is passed along to userspace. Also see this thread [1].

OK, so just to confirm there's nothing wrong with my other kernel parameters?

processor.max_cstate=0

intel_idel.max_cstate=0

panic=10

processor.max_cstate=0

intel_idel.max_cstate=0

These options should mean your machine will at most use C-state C0 and none of the intel_idle specific C-states, falling back to acpi_idle. This could mean that your machine uses more power than it might need to. However, if you don't really let it idle, and you are experiencing instabilities otherwise, setting this should b e fine.

panic=10

This just means that the kernel will wait for 10 seconds before rebooting when encountering a panic. It should be fine, but that might depend on your use case. If you don't experience any issues with this option, you can leave it as is.
