--- Comment #2 from Jonathan Nieder jrnieder@gmail.com 2011-08-05 10:19:10 PDT --- Hi Mikhail,

(In reply to comment #0)

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. http://www.youtube.com/watch?v=KtxRLEtHu5w

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.

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. :)
