No regressions noticed in either of my x8t_64 systms, aarch64 rpi 4b, i586 and vb guests. In the x86_64 laptop cpuinfo has ... cpu family : 23 model : 96 model name : AMD Ryzen 7 4800H with Radeon Graphics Running the zenbleed poc shows Spawning 8 Threads... zenbleed: failed to start thread on specifed code 1: Success before and after the kernel or microcode update.

cpu family : 23 model : 104 model name : AMD Ryzen 5 5500U with Radeon Graphics Installs cleanly, but does not contain fixes for this CPU. The journal still reports kernel: Zenbleed: please update your microcode for the most optimal fix No regressions noticed so far.

Mageia8, x86_64 AMD Ryzen 7 5700U 16 cores Installs OK. The journal after reboot issues same notices as in comment 2 and reports patch_level=0x08608102 for each CPU core. Too early for conclusion on regressions. None noted anyway.

MGA8-64 Plasma system, A8-4555M APU. Predates any kind of Zen, so is probably unaffected by this issue. Updated this and the kernel in one operation, no issues noted so far.
