Important

For Genoa (Family=0x19 Model=0x11) and Bergamo (Family=0x19 Model=0xa0), either AGESA version >= 1.0.0.8 OR a kernel with the following commit is required: a32b0f0db3f3 ("x86/microcode/AMD: Load late on both threads too")

Note	When late-loading the patches for Genoa or Bergamo, there may be one spurious NMI observed per physical core. These NMIs are benign and don’t cause any functional issue but will result in kernel messages being logged.

Note

When running 5.19+ kernels on Genoa or Bergamo systems, some microcode patches are known to trigger warnings in the PMI handler. The following are the required minimum patch levels to address this problem: Family=0x19 Model=0x11 Stepping=0x01: Patch=0x0a10113e Family=0x19 Model=0x11 Stepping=0x02: Patch=0x0a10123e Family=0x19 Model=0xa0 Stepping=0x01: Patch=0x0aa00116 Family=0x19 Model=0xa0 Stepping=0x02: Patch=0x0aa00212
