Logs ("dmesg" and "xorg.0.log" for kernels 3.2-rc4 and 3.1 with and without the
firmware installed)

1. Steps to reproduce the problem

Running Debian Wheezy, by installing the package "firmware-linux-nonfree" which
contains the firmware to enable 3D acceleration for the ATI card (M56P Radeon
Mobility X1600), when the system starts and user logins, the system crashes (no
specific action triggers the crash, is just about time to get it).

2. Symptoms

The user receives a "kernel oops" (kernel 3.1) or system hangs with a trace
(kernel 3.2-rc4) and system locks.

3. Tested kernels

The user has tested kernel 3.1 (Wheezy's stock kernel) and 3.2-rc4 (from
Debian's experimental branch). Both kernels expose the same result when
firmware is installed. On the other hand, both kernels work fine as soon as the
firmware package is unistalled.

4. Additional information

The crash has been tracked in Debian BTS #651532 (full link available in the
URL field).

5. Attached logs (4 files):

- "dmesg" and "Xorg.0.log" for kernels 3.2-rc4 and 3.1 when firmware is
installed.

- "dmesg" and "Xorg.0.log" for kernels 3.2-rc4 and 3.1 when firmware is not
installed.

6. Other considerations

Please, note that I am opening the this bug on behalf of another person who is
experiencing the crash. For this reason I'm CC'ing to him.
