Description Mark Cave-Ayland 2010-03-18 02:38:52 UTC
Hi,

We have a display issue with some new Acer Veriton L480G workstations we have recently purchased. They are currently built using Debian Squeeze and connected to large display monitors via DVI.

What seems to happen is about once a week, the display monitor goes totally black and so it is necessary to reboot/restart X in order to get it back. Using an SSH session I was able to get the following information as specified in the bug reporting guidelines:

Kernel: 2.6.32-trunk-amd64
Chipset: G43/G45
System (uname -m): x86_64
xf86-video-intel version: 2.9.1-2
X server version: 7.5+3
libdrm version: 2.4.18

Also attached are the following from when the workstation was in its faulty state:

intel_dmesg.txt:
    Contents of kernel dmesg

intel_gpu_dump.txt:
    Output of intel_gpu_dump utility

intel_reg_dumper.txt
    Output of intel_reg_dumper utility

intel_pci.txt:
    Output of "lspci -v" for graphics card

Xorg.0.log:
    X server log output


ATB,

Mark.

Logs indicate a potentially spurious GPU hang.

Do you still see this issue with more recent kernels and libdrm versions?

timed out on this one
