Photo of ACPI errors on laptop console

Fresh install of openSUSE 15.0 beta (30 April 2018) from  iso
openSUSE-Leap-15.0-NET-x86_64-Build228.2-Media.iso written to USB disk with
image writer.

Installation was on a (brand new) HP Probook 450 G5.

Initial setup was fine. When package installation started, I left. When I
returned a few hours later, the installation had stopped and the console showed
ACPI errors as shown on attached photo of laptop display.

The error must have happened fairly late in the installation procedure, because
after a reboot, openSUSE started fine and I have not experienced any problems
so far.
