Description Éric Fintzel 2017-05-04 09:02:20 UTC 
Description of problem:
When verifying correction of bug https://bugzilla.redhat.com/show_bug.cgi?id=1435154 by installing on LPAR.
The installation was successful on both ppc64 and ppc64le LPARs, but when rebooting at the end of installation, restart is not automatic for ppc64.
For ppc64le, the system reboot, the SMS menu appears, after the timeout grub appears and Fedora starts automatically up to the login prompt.
For ppc64 the LPAR reboot but does not start automatically, the SMS menu appears, then it appears a second time, when the  system disk is manually selected grub appears with automatic start of Fedora. It seems the system disk to boot is not identified automatically.

Steps to Reproduce:
1. Install Fedora 26 ppc64 on a LPAR
2. Reboot or start the LPAR

Actual results:
Installed Fedora does not boot automatically.

Expected results:
System should start automatically as for ppc64le.

Additional info:
Tested with following images:
Fedora-Server-dvd-ppc64-26-20170424.n.0.iso
Fedora-Server-dvd-ppc64-26-20170426.n.0.iso
Fedora-Server-dvd-ppc64-26-20170502.n.0.iso
The behaviour is the same for any successive reboot of the ppc64 LPAR.
The behaviour is the same for a graphical or text install.

Comment 1 Éric Fintzel 2017-06-08 08:56:06 UTC 
Unable to reproduce since a power outage in our lab and the restart of LPARs servers. Now ppc64 has the same behaviour than ppc64le.
