1) install ledmon on a Dell PowerEdge system with PCIe SSD hardware.
2) Startup ledmon (sudo ledmon)
3) Look in /var/log/syslog..you'll see messages such as the following repeated several times:
ledmon[2449]: Device (null) : No host_id!
ledmon[2449]: DETACHED DEV '(null)' in failed state
4) With the upstream patch in place and after restarting ledmon, the "no host_id" and "DETACHED_DEV" messages will go away and the PCIe SSD devices are detected correctly.
Without the fix, here's how to reproduce:
1) install ledmon on a Dell PowerEdge system with PCIe SSD hardware. syslog. .you'll see messages such as the following repeated several times:
