Linux Kernel 6.6 LTS CPU regression on i7 Alderlake

cpupower frequency-info:

analyzing CPU 9:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 9
  CPUs which need to have their frequency coordinated by software: 9
  maximum transition latency: 10.0 us
  hardware limits: 400 MHz - 2.60 GHz
  available frequency steps:  2.60 GHz, 2.60 GHz, 2.50 GHz, 2.30 GHz, 2.20 GHz, 2.00 GHz, 1.90 GHz, 1.70 GHz, 1.50 GHz, 1.40 GHz, 1.20 GHz, 1.10 GHz, 900 MHz, 700 MHz, 600 MHz, 400 MHz
  available cpufreq governors: conservative ondemand userspace powersave performance schedutil
  current policy: frequency should be within 400 MHz and 2.60 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 1.33 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes
