1.1.2.1  Booting the Installation System

https://doc.opensuse.org/documentation/leap/startup/html/book.opensuse.startup/art.opensuse.installquick.html#sec.opensuse.installquick.boot

Hello - 

This is a bug description with a workaround that can be added to the OpenSUSE
documentation on installation.

The bug is: "installation fails (hangs or crashes) on Asus G20/GB20 ROG models 
and may also affect other recent x86_64 machines with dual Intel and nVidia
graphics"

The version tested is:
openSUSE-Tumbleweed-DVD-x86_64-Snapshot20190425-Media.iso 

Notes:
1. PCI Advanced Error Reporting (AER) floods system logs making system and
installer unresponsive, also makes copying log
files in the last steps of installation (from USB updater) frequently fail.
2. Hard crash occurs typically at last steps of installation, which causes the
hard drive to become corrupted.  The cause is unknown to me, but acpi=off
solves the problem.


Work-around for Installation and Upgrade:
For both "Installation" and "Upgrade" options on the USB stick or DVD boot,
press 'e' and add these
kernel parameters:

acpi=off nomodeset

I recommended that these parameters be defaulted for the installation and
upgrade boot loaders from USB or DVD.  Otherwise installation will fail with
hard crash at the end (after a lot of time was already taken).

Work-around for hard-drive boot:

After the new system is booted, add these kernel parameters using 
YaST / system / boot loader / kernel paramters:

acpi=pci pci=noaer

This will make the work-around fix permanent.
Tested on a 2017 ASUS GB20 x86_64 with both Intel and nVidia graphics.

Thank you for checking this.

Comment:  I think OpenSUSE is a great Linux product.  The installation process
on newer machines with complex ACPI and dual graphics cards seems partly
broken,
since it fails out of the box, and a lot of time and reading is needed to
get it to work.  I saw at least one press article lamenting this problem and
downgrading OpenSUSE.  Therefore, to encourage new users, who perhaps cannot
solve this problem at all, it would be great if this can be checked soon!  
perhaps with the suggested documentation note above added until this can be
fixed in a more automatic way.

Maybe documentation section 1.1.2.1 isn't the perfect place for such a note,
but it should be near the top so new users will see it!

Again, many thanks - on behalf on the new users installing OpenSUSE on these 
kinds of machines.

Regards,

David
