Thanks. As this issue is seen with the 4.15 Bionic (18.04) kernel, I'll
update the tags and title accordingly. From Frank's comment above, I
think we can assume that this is fixed in Focal (20.04).

So should this bug be moved to kernel to get the fixes be made available to
Ubuntu 18.04 release or should we keep this bug opened for skiboot under OPAL
itself, since we are already in the upstream level of skiboot installed on the
system.

The patch in comment #7 was included in a test pnor driver -
op999.1999.20190423t - that was provided to ISST to look at several
skiboot pending changes. This defect was also seen in System Mfg Test
- so this patch should be merged for OP930 GA.

Anju,
Where are we with this patch? Did you push changes to upstream?
Also is this really a ship issue?
