And there I was happy to purchase an AMD Ryzen laptop a few months ago. After the laptop keyboard problems (very slow typing due to faulty IRQ overrides, Mario Limonciello submitted a patch but it's still not part of any stable release, you have to patch the sources yourself), now it turns out the occasional stuttering is also because of AMD.

Update your bios. A new driver update has fixed this.

Linux kernel 6.2 fixed this too I think

My BIOS is up-to-date and no the 6.2 doesn't fix it. Mario himself said his patch will be part of one of the 6.5 rc's (and it looks like it's already part of the current rc). Until then, anyone with a recent Ryzen CPU and a laptop keyboard needs to apply the patch manually on the current versions.

And here's me with a Huawei laptop where I can't upgrade the BIOS. I've had to completely disable fTPM just to stop the freezing.
