Bug Description
First of all:
I cannot find out how to report bugs without using the command "ubuntu-bug".
As I need to have a running kernel to use this method I have run "$ubuntu-bug linux" on another kernel than the one I wish to report the bug on...
The kernel I have reported this bug on is running with "radeon.modeset=1" on 2.6.31-11.38 with a dual head ATI card.
The kernel I hangs on 2.6.31-12.41 with the same card and configuration.
A regression seems to have occurred between these kernels. No revealing logs were present. The last statement was:
First time:
Oct 8 09:45:50 nsh-ubuntu kernel: [ 20.776080] Unpin not necessary for ffff88013653f600 !
Second time:
Oct 8 09:49:27 nsh-ubuntu kernel: [ 21.604822] Unpin not necessary for ffff880135de4a00 !
The secondary screen goes dark, and the kernel freezes.

We are not expecting KMS to be stable for all ATI cards in 2.6.31 and not enabling it there by default for Karmic. That said if it worked on 2.6.31-11.38 then I am supprised it does not do so on .41 as I cannot see any radeon changes in the kernel between those two versions.
Can we try booting the .41 kernel without modeset enabled and without quiet to see if we get to see something prior to the panic. Also there was one tty related panic in .41 which was fixed in subsequent kernels. So does this occur with the latest available kernel .42 and later? Again if it occurs with modeset can we try booting without modeset and without quiet there.
Please report back here. Thanks.
