[SOLVED] Radeon HD 6850 corrupted graphics

Hi,

Since yesterday I noticed strange behavior. Some icons are corrupted and display seems unresponsive.

Here is a part the output of dmesg :

[  126.967455] radeon 0000:01:00.0: evergreen_surface_check_linear_aligned:215 texture pitch 952 invalid must be aligned with 64
[  126.967459] radeon 0000:01:00.0: evergreen_cs_track_validate_texture:830 texture invalid 0x0ee81d81 0x1000028c 0x0a0a0000 0x00000000 0x00000000 0x8003001a
[  126.967475] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream !

Full dmesg here

Do you have already encoutered this issue ?

Edit : Applications like Keepass/Virtualbox/Steam increase the problem.

Hi,

It happens again today. The dmesg is pretty similar.
I notice, a reboot is not enough to correct the issue. A full shutdown (wait few minutes or manually purge power) seems necessary to correct the problem.

Here is the list of upgraded packages before the problem appears the first time:

[2016-10-05 18:25] [ALPM] upgraded libxfixes (5.0.2-1 -> 5.0.3-1)

Re: [SOLVED] Radeon HD 6850 corrupted graphics

Looks like it could be this bug: https://bugs.freedesktop.org/show_bug.cgi?id=94901

Are you using stock mesa and xf86-video-ati ?
Please post xorg log along with the content of any *.conf files in /etc/X11/xorg.conf.d/ folder

clean chroot building not flexible enough ?

Re: [SOLVED] Radeon HD 6850 corrupted graphics

Hi,

Yes I use mesa and xf86-video-ati.

cat /etc/X11/xorg.conf.d/* :

# Read and parsed by systemd-localed. It's probably wise not to edit this file
# manually too freely.
Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbLayout" "fr"
        Option "XkbVariant" "oss"
EndSection
Section "Device"
	Identifier  "Radeon"
	Driver "radeon"
	Option "ColorTiling" "on"
	Option "ColorTiling2D" "on"
	Option "DRI" "3"
	Option "TearFree" "on"
EndSection

I don't have the log during the bug. Here is the actual Xorg.log don't sure if it's useful. I will edit the post if it's happening.

Re: [SOLVED] Radeon HD 6850 corrupted graphics

Xorg log shows your card uses EXA (default for pre-radeonsi cards) but you also enabled DRI 3 .
I think that's the first time i've seen that combo.

try adding Option "AccelMethod" "glamor"  .
