[Bug 531635] [NEW] Kernel oops with radeon module, kernel modesetting fails

[pirx67]

Public bug reported:

I'm trying to test the Lucid Lynx Alpha 3 version. When booting the
kernel modesetting that is tried in the radeon module leads to a NULL
pointer dereference.  This affects later also the Xorg process. After
some time the boot stalls. No tty console, no Xorg, gdm etc.

The system is then dead. No reaction on CTRL-ALT-DEL keys.

I managed to log the kernel output by setting the console to /dev/ttyS0
and log the output on another computer. See the attached file
lucid_a3_boot.txt.

The apport bug report was created after a successful boot with kernel
modesetting disabled (nomodeset on the boot chooser screen).

I hope the gathered information is enough. If not please contact me.
