Fresh install of Ubuntu server 24.04 on the Server with Intel VMD 2. Upgrade the kernel to 6.8.0-40 and install the ledmon package 3. Locate the LED of nvme device behind Intel VMD with the following command: # ledctl locate=/dev/nvme0n1 or ledctl locate=/dev/nvme0n1 --listed-only [Fix] After checking the source code, Lenovo noticed it ran into the issue from the kernel commit abaaac4845a0d6f39f83cbaba4c3b46ba5f93170. This patch (5560a612c20d3daacbf5da7913deefa5c31742f4) which is now upstream resolves this issue.
