@kaihengfeng Following instructions here, https://wiki.ubuntu.com/Kernel/MainlineBuilds I've installed generics, rebooted, and was welcomed to the blinding white void. Hazarding a guess, I typed in my system's encryption password and it subtly changed brightness like it usually did and a mouse cursor appeared. So that's something. Switching to a virtual console still was white but I was able to blindly login and type in `sudo reboot now` and switch back to a stable kernel.
Removing a workaround employed here, https://forums.lenovo.com/t5/Other-Linux-Discussions/ThinkPad-E485-E585-Firmware-bug-ACPI-IVRS-table/td-p/4191484 particularly the `ivrs_ioapic[32]=00:14.0` line didn't resolve and just left me hung after GRUB like it did normally. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1848108 Title: [amdgpu] Screen Glitching & Kernel Panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848108/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
