I regularily fit the RX460, but keep running into issues, crashes and others, that force me to install the HD6670 again if I need my computer for serious work or even a more stable gaming situation. However, = I am making progress identifying issues, and it looks like there are 3 different causes for crashes. One of them I can now reproduce very easy, and smells l= ike a real driver bug, so therefore I would like to report it. My hardware is as follows: Xeon E5-2650v2 CPU (once it was an Opteron, but you stopped making new one= s :( ) Supermicro X9SRE-3F mainboard 32GB RAM HIS Radeon RX 460 2GB 3 * HP LP2065 1600x1200 monitor - One connected via active DP to DVI converter - One connected via DVI - One connected via HDMI to DVI cable My software configuration is as follows: OpenSuSE 13.1 with the following modifications: - Amd-staging-4.7 kernel as of 21 december 2016 (compiled it myself) (DAL is needed to use all my 3 monitors) - Xorg upgraded to 7.6 (via http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_13.1/ ) - Mesa upgraded to 13.0.1 (via http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_13.1/ ) How to reproduce? Using the game The Great Whale Road, I have captured the OpenGL command str= eam with Apitrace: http://apitrace.github.io/ I have uploaded it here, be warned that this is a 770MB download: http://www.freepascal.org/~daniel/greatwhaleroad.trace.bz2 Then: bunzip2 greatwhaleroad.trace.bz2 apitrace replay greatwhaleroad.trace At the end of the replay, all monitors lose signal and go black. Because my mainboard has a small Aspeed onboard VGA controller, I can switch my monitor input to that VGA controller, login to the Linux VGA text console and recov= er some information. In dmesg the stack trace below is visible. You can also s= ee that the X server and game processes are still running, but hanging inside = the kernel, so they cannot be killed.

Complete syslog data from boot to crash

Hello,

I am in the process of migrating from a Radeon HD6670 to an RX 460 for quit=
e a
few months now. I regularily fit the RX460, but keep running into issues,
crashes and others, that force me to install the HD6670 again if I need my
computer for serious work or even a more stable gaming situation. However, =
I am
making progress identifying issues, and it looks like there are 3 different
causes for crashes. One of them I can now reproduce very easy, and smells l=
ike
a real driver bug, so therefore I would like to report it.

My hardware is as follows:
 Xeon E5-2650v2 CPU (once it was an Opteron, but you stopped making new one=
s :(
)
 Supermicro X9SRE-3F mainboard
 32GB RAM
 HIS Radeon RX 460 2GB
 3 * HP LP2065 1600x1200 monitor
  - One connected via active DP to DVI converter
  - One connected via DVI
  - One connected via HDMI to DVI cable

My software configuration is as follows:
 OpenSuSE 13.1 with the following modifications:
  - Amd-staging-4.7 kernel as of 21 december 2016 (compiled it myself)
      (DAL is needed to use all my 3 monitors)
  - Xorg upgraded to 7.6  (via
http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_13.1/ )
  - Mesa upgraded to 13.0.1 (via
http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_13.1/ )

How to reproduce?

Using the game The Great Whale Road, I have captured the OpenGL command str=
eam
with Apitrace:

http://apitrace.github.io/

I have uploaded it here, be warned that this is a 770MB download:

http=
://www.freepascal.org/~daniel/greatwhaleroad.trace.bz2

Then:

bunzip2 greatwhaleroad.trace.bz2
apitrace replay greatwhaleroad.trace

At the end of the replay, all monitors lose signal and go black. Because my
mainboard has a small Aspeed onboard VGA controller, I can switch my monitor
input to that VGA controller, login to the Linux VGA text console and recov=
er
some information. In dmesg the stack trace below is visible. You can also s=
ee
that the X server and game processes are still running, but hanging inside =
the
kernel, so they cannot be killed.

Best regards,

Dani=C3=ABl Mantione
