I've had a weird system-wide stutter for months and the usual googling and troubleshooting didn't help.. omg. This might be it. Thank you Linus and thank you op.

I had it on my Windows 11 PC for a long time. I use this PC for music production and it was infuriating - the sound would just cut out intermittently like the computer couldn't keep up. I tried lots of things, including an expensive CPU upgrade. In the end Asus released a new BIOS for the motherboard to address this AMD stutter, and that fixed it.

Which AGESA version?

Which AGESA version?

I don't really know anything about that. Currently HWiNFO64 shows Microcode Update Revision A201025 and SMU Firmware Revision 56.74.0. I don't know whether those are the numbers you're asking for, or what they were while it was still having problems.

Thanks for the info! I'll have to check that against what I'm using.

The issue is worked around in newer kernel versions. But it's better to just update your BIOS to fix the issue.
