Hello,

I have an issue with the GMA500 driver for kernels from 3.5 up to 3.7-rc4.
I am using an Intel board with a D2700 Atom processor running Debian unstable.
Sometimes when DPMS switches off the screen the system reboots. More often it
does not reboot but shows a white screen on reactivation. Then I can ssh into
the box from another host but the white screen remains even if I restart X or
change VT. This never seems to happen the first time the screen is switched off,
generally it takes 3 or 4 cycles to trigger the bug. Kernel 3.4.3 works fine.
There are no messages in the logs. Any idea what might cause this or how I
can debug it any further? I will supply more details on my setup if needed.
Please CC me in your reply as I am not subscribed to the list.

Thanks in advance
                 Georg Chini

If 3.4.3 works and 3.5 fails then that is a big help as it narrows the
possible range of causes down quite a bit.

Hardware info would be helpful here but I suspect it may be a case of
doing a set of test builds to identify the offending patch.

Also anything in the log might be helpful including doing the runs with
drm.debug=255 in the kernel command line to get full traces

See attached file. I removed the bit where I tested switching off/on for a while, there
is no additional information. When the error occurs I find following additional lines
in the log:

Nov  9 14:53:12 pico kernel: [drm:drm_crtc_helper_set_config],
Nov  9 14:53:12 pico kernel: [drm:drm_crtc_helper_set_config], [CRTC:3] [FB:61] #connectors=1 (x y) (0 0)

Nov  9 14:53:12 pico kernel: [drm:drm_crtc_helper_set_config], [CRTC:4] [NOFB]

Do you need any more information?

Regards
