Hi Hussain, how has the 2.6.38-4 kernel been holding up?
It sounds like this is a regression in the kernel drm code.
If the issue is still occurring with the latest kernel, then avivotool
can be used to assist in debugging this issue. avivotool is provided
with the radeontool package, so to install it run:
sudo apt-get install radeontool
After installing it, you run it like this:
avivotool regs all > regdump_good.txt
avivotool regs all > regdump_broke.txt
Run it two times. Once when you have a working screen (for any kernel),
and once in the broken case (either from the tty console or logged into
the sick box remotely). Attach both of those to this bug report, and we
can then forward this issue upstream. Thanks ahead of time!
