[Kernel-packages] [Bug 1776563] Re: Ubuntu 18.04 can't load kernel on Acer Aspire A315 (Ryzen5/Radeon/FHD)
Had this on my A315 too, but I returned it to the vendor. Seems to be an UEFI-Bug, because it doesn't happened with my Ryzen 2500U from HP. Could also be related to that Ryzen/Radeon 535 combination (Vega/CGN 3). On Grub-Menu press E and add "pci=noacpi" as kernel-parameter (where normally "quite splash" is). Then go on booting by pressing F10. Sometimes (XFCE) it was also necessary to add "nomodeset" to boot, Gnome for example didn't need it (AFAIK). I remember, I also needed to install amd's pro driver (for 18.04) via amdgpu-pro-install to get rid of the "nomodeset". I was able to run amdgpu-pro-uninstall later and still not needed the "nomodeset". Could be related to my system, but you may give it a try. I was also using Kernel 4.17 (Mainline), which is available on http://kernel.ubuntu.com/~kernel-ppa/mainline/ or with UKUU https://www.omgubuntu.co.uk/2017/02/ukuu-easy-way-to-install-mainline-kernel-ubuntu -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1776563 Title: Ubuntu 18.04 can't load kernel on Acer Aspire A315 (Ryzen5/Radeon/FHD) Status in amd: New Status in linux package in Ubuntu: Confirmed Status in xserver-xorg-video-amdgpu package in Ubuntu: Confirmed Bug description: CPU: Ryzen 5 2500U VGA: Radeon 535 Notebook: Acer Aspire A315 I've just bought a new AMD Ryzen/Radeon notebook (Acer Aspire 3) and I wanted to install an Ubuntu/Kubuntu 18.04 on it.
