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:
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:
Contents of kernel dmesg
Output of intel_gpu_dump utility
Output of intel_reg_dumper utility
Output of "lspci -v" for graphics card
X server log output

Kernel dmesg output
Created attachment 34188 [details]
Created attachment 34189 [details]
Created attachment 34190 [details]

X server log file
Logs indicate a potentially spurious GPU hang.
Do you still see this issue with more recent kernels and libdrm versions?
