Description Justin Clift 2019-09-15 06:17:08 UTC
Trying to sort out a system stability problem with my new laptop (Acer Nitro 5, model AN515-42-R3EE) with Ryzen 2700U and RX560X.

dmesg output shows traceback for amdgpu with kernel 5.3-rc8, all prior kernels I've tested (various 4.x, and 5.3-rc7) also have various tracebacks shown in amdgpu.

Here's the 5.3-rc8 kernel one, note there are several that show up at the same time in the dmesg output, all amdgpu related:

***********************************************************************

I'm ok with applying and testing kernel patches if need be. ;)
Comment 1 Robert Hoffmann 2020-01-03 15:52:27 UTC
Hi guys,

I am getting a very similar issue with a Ryzen 3400G  (AMDGPU).

OS Fedora 31: Linux asrock 5.3.16-300.fc31.x86_64 #1 SMP Fri Dec 13 17:59:04 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

The problem manifests itself every time I enter into an Xorg (LXDE) session, I guess one time per CPU core. So I am getting 10-12 errors every time I log in, as popups.  Xfce also will not work at all, only LXDE (Openbox) seems to work fine.

Operationally all seems relatively OK though, except if I turn off one of my 2 monitors, and turn them back on, I will get the errors again.


I dont have a kernel debugger or profiler installed.

-------- here is a snippet of a backtrace: -------------

Quick update:  there is also a bug in Redhat bugzilla, which is directly repated:
Bug link: https://bugzilla.redhat.com/show_bug.cgi?id=1786489

BTW, this happens both on the Display Port and the HDMI port.
Comment 3 Justin Clift 2020-01-04 09:14:28 UTC
As an extra data point with this, the error in my case only happens when I have an external monitor plugged in via the HDMI port.

This is on a laptop, with the error not showing up if only the in-built display is in use.  eg the HDMI not even plugged in.
Comment 4 Justin Clift 2021-08-22 07:37:36 UTC
Clearly no-one is ever going to look at this, so I'm just going to close it.
