kernel log file

This issue ocurred when I updated kernel version 2.6.38-2-686-pae to
2.6.39-2-686-pae version.
- The GPU's device ID: 1002:9712 (M880G, Mobility Radeon HD 4200)
- The model name: Acer Aspire One 521
- I am using Debian testing (wheezy) x86 
- Also system couldn't enter in single mode, because screen goes dark again.

I attach link to youtube video that's demonstrates symptoms of this issue.

Thanks.  If you have time, could you bisect to find the change that introduced
this bug?

It works like this:

0. Write a script named "as" with the following content and put it in
your $PATH to work around <http://bugs.debian.org/620448>.

    #!/bin/sh
    exec /usr/bin/as --size-check=warning "$@"

1. Grab the latest mainline source:

 # apt-get install git build-essential
 $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
 $ cd linux

2. Minimal configuration.

 $ make localmodconfig

3. Test.

 $ make deb-pkg
 # dpkg -i ../<name of .deb>
 # reboot

4. If it works, let us know and declare victory. Otherwise:

 $ git bisect start v2.6.39 v2.6.38 -- drivers/gpu

Git will check out a version half-way between to test.

 $ make silentoldconfig; # reuse configuration
 $ make deb-pkg
 # dpkg -i ../<name of .deb>
 # reboot
 $ cd ~/src/linux
 $ git bisect good; # if it works
 $ git bisect bad; # if it fails in the same way
 $ git bisect skip; # if some other bug makes it hard to test

5. Git will check out a next version to check; repeat step 4 until
it gives the "first bad commit" or you get bored.  If you finish
early, you can send the output of "git bisect log" to let us know
the information acquired so far.

If gitk is installed, at any step you can run "git bisect visualize"
to see the regression range narrowing.

Hope that helps.

Sorry I missed your message before.  Do you mean that you don't have a working
kernel installed in addition to the broken one?

After this when my system has broken with updated kernel I decide
reinstall system. Now I have system only with new unworkable kernel.
Also I try new debian wich build at 22-Aug-2011 with kernel
3.0.0-1-686-pae. Problem not fixed yet.

It would _really_ help to have a working system.  Could you try
installing Debian squeeze and then just upgrading the kernel?

Alternatively, it might be possible to do experiments using a live
CD[*], but I don't know how to swap out the kernel there.

Debian 6.0.3 (squeeze) can boot without described issue with linux
kernel 3.1.0-rc9+ but without usb and network support :(
How enabling usb and network support???

Thanks for testing; that's good news.  You can configure the choice of
drivers for a linux build with "make nconfig".

Administrivia:

 - can you reproduce the bug with a 2.6.39 kernel on squeeze?
   If not, that would mean there is some complicating factor other
   than the kernel.

 - does a distro 3.x kernel[1] also avoid the bug?  If not, please
   attach the .config file from the 3.1.0-rc9+ build you tested with.

[1] e.g. from <http://wiki.debian.org/DebianExperimental>.  It would
include usb and networking support. :)

I has downloaded from this location
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.39.4.tar.bz2
linux kernel compiled and works fine! Also without issue with screen
and with usb and network support.

Seems this is not problem in kernel.
