Hi, I updated the bug last week, I'm not sure how I ended up reverting
those changes, but the current version in the test PPA should work,
here's the diff from that latest upload:

>   The LEDCTL and LEDMON applications are design to work on both AHCI and SCU.

>   Also, new version of ledmon adds the functionality of blinking LED with NVMe under VMD domains.
>   The LEDCTL application is similar to SGPIO but the major difference is that LEDCTL (as well as LEDMON) has the internal logic built in and this means it is aware about RAID devices present in the system.

>   The ledctl is user space application design to control LEDs associated with each slot in an enclosure or a drive bay. There are two types of system: 2-LEDs system (Activity LED, Status LED) and 3-LEDs system (Activity LED, Locate LED, Fail LED). User must have root privileges to use this application.
