System incredibly slow after kernel update

After the latest kernel update, my laptop has become incredibly slow.
OS: Arch Linux
Kernel Version: 6.0.11-arch1-1

While auto-cpufreq is running, my cpu frequency on all cores seems to go down as far as 409 Hz.

I did stumble upon [this reddit post](https://www.reddit.com/r/archlinux/comments/zccknj/the_latest_kernel_6011arch11_has_made_my_laptop/) which identified the issue as the new AMD p-state driver. But I didn't see the error reported here, so just passing it along.

As of now, I've had to disable auto-cpufreq to get a usable system.
