Comment 390 for bug 1776563

 Distro I'm running is Fedora 29 on an A315-41. Now under 4.19 kernel, no ivrs args needed, Touchpad works, secure boot, WiFi, etc. works. Overall, the most stable this laptop has ever been. Kernel 4.20, softlocks immediately upon boot, need to add ivrs args back and acpi goes to physical flat. Touchpad still works. Now for living on the edge, vanilla mainline git 5.1x, still need ivrs args, touchpad does not work, and cursor tearing in middle half of screen. Ugh. This is more of a regression than 4.20 was. I had Debian Working with backported 4.18 and updated amd firmware blobs, I could never get Ubuntu to work at all.
