http://bugzilla.opensuse.org/show_bug.cgi?id=1137147 Bug ID: 1137147 Summary: [doc] 1.1.2.1 Booting the Installation System Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: x86-64 OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Bootloader Assignee: jsrain@suse.com Reporter: drsoaring@gmail.com QA Contact: jsrain@suse.com Found By: --- Blocker: --- 1.1.2.1 Booting the Installation System https://doc.opensuse.org/documentation/leap/startup/html/book.opensuse.start... 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.
