Bug ID: 111122
Summary: 2500U: Graphics corruption on kernel 5.2
Product: DRI
Version: XOrg git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu

Kernel log
Arch Linux
Lenovo E485 (16 GiB RAM)
AMD Ryzen 2500U
xorg-server 1.20.5-2
mesa 19.1.2-1
xf86-video-amdgpu 19.0.1-1
libdrm 2.4.99-1
After upgrading to the linux kernel 5.2 from the Arch Linux repositories, my
laptop started to show graphical corruption in Firefox or Konsole. It is much
worse if something is moving on the screen e.g., a video is playing. Sometimes
Firefox is almost unusable as a result. A downgrade to 5.1.16 immediately fixes
the issues.
Somebody mentioned similar corruption for bug 109206:
https://bugs.freedesktop.org/show_bug.cgi?id=109206#c57
My kernel command line is:
initrd=\amd-ucode.img initrd=\initramfs-linux.img
root=PARTUUID=34098e4c-f1bf-4a43-a0a8-2ba3ed3c71a6 idle=nomwait
psmouse.synaptics_intertouch=1 acpi_osi=Linux amdgpu.gpu_recovery=1
ivrs_ioapic[32]=00:14.0
I used to have iommu=pt or iommu=off on the command line to get this laptop to
boot properly but I have not needed that switch for a while. I might try to
reintroduce it with 5.2 just to see what happens. In any case, my setup worked
before, so something does not seem right.
