I ran

# python3 zenstates.py --list
...
C6 State - Package - Enabled
C6 State - Core - Enabled
# python3 zenstates.py --c6-disable
Disabling C6 state
# python3 zenstates.py --list
...
C6 State - Package - Disabled
C6 State - Core - Disabled

So, it looks all successful. But in the dmesg output I see the lines

[  221.257615] msr: Write to unrecognized MSR 0xc0010292 by python3 (pid: 2669).
[  221.257623] msr: See https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/about for details.

What does this mean?

I'm using an AMD Ryzen 7 4800U with Radeon Graphics CPU with an Ubuntu 22.04 distro (kernel: Linux 5.15.0-40-generic).
