throttled: I/O Error: fatal('Unable to read to MSR {:x}. Unknown error.'.format(msr))

Hi, the issue you fixed on https://github.com/erpalma/throttled/issues/236 is still going by my side Kernel 5.10, arch linux, HP Pavilion Power CB035NF, lsm lockdown removed… I commented the HWP_Mode line in the config but it change nothing

rdmsr -a 0x774 rdmsr: CPU 0 cannot read MSR 0x00000774

Same on systemctl status

I have the latest version of lenovo_fix, and the HWP_Mode is commented in config (/etc/lenovo_fix.cfg)

What can i do ? Thanks
