[Bug 1478513] Comment bridged from LTC Bugzilla
------- Comment From sesmith@xxxxxxxxxxx 2015-09-30 22:24 EDT-------
I don't know why there's a Fix Potential of P810.00D, this is an Ubuntu kernel issue and has nothing to do with any release anywhere named P810.00.
this is probably yet another example of the bug bridge breaking in
stupid ways.
Sorry Ubuntu peeps - I'll attempt to poke someone internally.

The following message is being posted to the linux message log on Firestone systems, and we need to know what action to take.
- is this caused by a code bug that needs to be fixed?
- does the message indicate a real hardware problem?
or can the message be ignore?
Until we here otherwise, manufacturing is ignoring this message

"SYSPARAM: Opal sysparam node not found" we get this warning on firestone system for every boot because For OpenPower BMC machines we do not place any sysparams in the device tree.
This issue is addressed in the attached patch and patch is available in upstream.
We need to backport following patch in ubuntu to address this issue.
