Bug#599927: Kernel crashes when I start X on my Dell Latitude D505

[Petter Reinholdtsen <pere@hungry.com>]

Package: linux-image-2.6.32-5-686
Version: 2.6.32-23
Severity: important

The X server involved is as far as I know xserver-xorg-video-intel
version 2:2.9.1-4.

When I install the current Squeeze on my test laptop, a Dell Latitude
D505, starting kdm kill the machine.

This is what happen when I start X manually when logged in via ssh:

  root@pxe-test0-pre:~# X

After this, the network connection is dead and the screen and keyboard
on the laptop is black and dead.

I was a similar problem with Ubuntu earlier, reported at
<URL: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/592682 >.

As the workaround for Ubuntu mentioned the file
/etc/modprobe.d/i915-kms.conf and changing modeset there, I tried to
change the current 'modeset=1' to 'modeset=0' and ran
'update-initramfs -u' before testing a reboot, but the problem was
still there.

Not quite sure what more to test.  Any suggestions?  I'm unable to get
any kernel messages from the crash.  Tried tailing /var/log/syslog
over ssh, but no messages showed up.

Happy hacking,
