Linux cpufreq/amd-pstate-ut - kernel panic when loading the unit-test driver: Loading the amd-pstate unit-test module
Impact
Loading the amd-pstate unit-test module panics the kernel. A test module shipped in production kernels that crashes the host when loaded - relevant because automated hardware-validation tooling on a new GPU fleet is exactly the thing that loads every available module to see what happens.
Who can reach it
Local, requires the ability to load the amd_pstate_ut module - so root, or automated burn-in tooling running as root.
What to do
Distro kernel update plus reboot. Meanwhile, keep amd_pstate_ut out of any module-loading sweep in your node acceptance testing.
