ATI FirePro M7740 went unstable - any ideas?

**suse_rasputin** · 20-Nov-2017, 13:48

Hi again!

Have an old Dell Precision M6400 with an ATI FirePro M7740 graphics, doing fine with TW 64bit KDE for months, but since about ernel 13.10 the machine crashes, the display turns background colour, icons dissapear and never turn up again. Hard crash, no console on e.g. CTRL+ALT F2 functionally (tried it even blind to login and reboot), only with power button can return to normal.

In the beginning, it was once a week, now we are at several times a day. It has nothing to do with the actuall install of TW, tried a rather fresh install on an USB-stick, same crashes.

With Win7 (dual boot) graphics is stable with the latest Dell/AMD driver. Unfortunately there is apparently no Linux driver for this graphics card:

Any ideas how to get this nice old system healthy again?

Hi
If you check the output from /sbin/modinfo radeon and look at the parm options, you may have to do some tweaking.... there are lots...

Hi
You can see what the current settings are via systool (as root user)

Code:

systool -vm radeon

...apparently a really rare piece of hardware only used in Dell Precision M6400 and M6500... sigh...

https://www.notebookcheck.net/ATI-Fi...0.18791.0.html

https://en.wikipedia.org/wiki/List_o...ocessing_units

Mobility Radeon HD 4860 and Radeon HD 4750 uses the same RV740 "architecture"...

**suse_rasputin** · 21-Nov-2017, 01:40

Is the "libvulkan_radeon" the driver used under TW? Any chance to try the older 17.2.4 version of this driver from anywhere? :-)

Hi and thanks!

I have a file "10-amdgpu.conf":

Code:

Section "OutputClass"
    Identifier "AMDgpu"
    MatchDriver "amdgpu"
    Driver "amdgpu"
EndSection

What would be safe to test here?

**malcolmlewis** · 22-Nov-2017, 06:17

Hi
Your system isn't using amdgpu, it's radeon...

**suse_rasputin** · 22-Nov-2017, 06:38

Hmm, but I don't have any radeon files in /etc/X11/xorg.conf.d, only a 50-device.conf:

Code:

# Having multiple "Device" sections is known to be problematic. Make
# sure you don't have in use another one laying around e.g. in another
# xorg.conf.d file or even a generic xorg.conf file. More details can
# be found in https://bugs.freedesktop.org/show_bug.cgi?id=32430.
#
#Section "Device"
#  Identifier "Default Device"
#
#  #Driver "radeon"
#
#  ## Required magic for radeon/radeonhd drivers; output name
#  ## (here: "DVI-0") can be figured out via 'xrandr -q'
#  #Option "monitor-DVI-0" "Default Monitor"
#
#EndSection

...but apparently everything is commented-out here, or?
