ThunderX BMC initialization failure

[Itaru Kitayama]

Hi,

We're seeing below on our ThunderX

$ sudo systemctl start ipmi
Job for ipmi.service failed because the control process exited with 
error code. See "systemctl status ipmi.service" and "journalctl -xe" for 
details.
$ sudo journalctl -xe
...
-- Unit ipmi.service has begun starting up.

...

Is it caused by the IPMI driver that comes with CentOS 7 or the BIOS?

Thanks,

Itaru
