Public bug reported:
[Impact]
This will cause the installer to exit early, causing a kernel panic before any
prompt to the user. This is restricted to some Power systems.
[Test case]
A build vmlinux was used to boot the installer, and a prompt was available.
'add' was written to /sys/devices/vio/uevent was written to, and no error was
found.
'add' was written to /sys/devices/vio/*/uevent, and modalias information was
found when 'udevadm monitor -p' was run in the background.
[Regression potential]
Events may be missing and coldplug/hotplug of vio devices may fail. That was
tested in the test case and not found to be the case.
