Description Philip Armstrong 2018-09-29 20:17:49 UTC
I'm seeing this oops on every boot, consistently ever since this hardware started consistently coming up at all.

Hardware is;

Gigabyte AB350N-Gaming WIFI/AB350N-Gaming WIFI-CF, BIOS F23.
8Gb RAM
Ryzen 5 2400G Vega.
Kernel 4.19-rc5 (but this oops has been there ever since the hardware started working consistently somewhere in the early 4.19-rc releases.)

Display is Dell U2518D 25" 2560x1440 connected via Displayport.

Forgot to mention: amdgpu firmware is latest from linux-firmware git.

also seeing this on my AMD Ryzen 5 2400G with Radeon Vega Graphics with kernel 4.19.0
Comment 4 vladi 2018-10-26 19:08:22 UTC
Forgot to mention system locks up as well at random after new 4.19.0 kernel
