I can't make gpu and suspend work at the same time on Acer A315 41G R6IM with Ryzen 2500U and Radeon 535.
If I use pci=noacpi gpu works fine, but laptop hangs on suspend, if I use ivrs_ioapic... suspend works fine but with no 2d gpu acceleration - everything works sluggish, very high cpu on scroling or moving windows etc., since, obviously, cpu does the work. Tested kernel: ubuntu 18.04 with 4.15 kernel ubuntu 18.04. with 4.18 hwe kernel and hwe stack also tried 19.04 from daily builds with no success, obviously gpu patch still didn't make it to kernel in 19.04 daily builds. Tested kernel params: ivrs_ioapic=00:14.0 ivrs_ioapic=00:00.2 clocksource=hpet iommu=on amd_iommu=on amdgpu.dc=1 amdgpu.runpm=0 radeon.modeset=0 amdgpu.dc=0 ... other kernel arams mentioned in this thread Any ideas on how to make Vega gpu run properly with ivrs_ioapic=00:14.0 ivrs_ioapic=00:00.2 (basically I don't need radeon 535 at all since I don't play games, I only need 2d acceleration for X) ? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1776563 Title: Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs, can't load, kernel freeze (AMD Ryzen 5/Radeon/Raven) / AMDGPU Hybrid crash Status in amd: Fix Released Status in Linux: Incomplete Status in linux package in Ubuntu: Triaged Status in linux-firmware package in Ubuntu: Confirmed Bug description: CPU: Ryzen 5 2500U VGA: Radeon 535 Notebook: Acer Aspire A315 This is a brand new notebook on the market with Ryzen 5/Radeon.

Soft lockup Using pci=noacpi kernel parameter kernel loads without any problem but my notebook produces more heat than on Win10. If I know right Acer notebooks need ACPI to the correct power management. The same thing happens on mainline 4.17,4.18rc1-2. BIOS upgrade to the latest version: 1.08 hasn't helped This problem has been reported upstream: https://bugzilla.kernel.org/show_bug.cgi?id=200087 The latest correctly working kernel was 4.13.* but the heat problem was present with this too.
