KMS with Radeon HD4350 causes system to lock up completely

[Jochen Schroeder]

Binary package hint: xserver-xorg-video-ati

Using KMS with a Radeon HD4350 (MSI) causes the system to lock up completely. The screen is blank, no changing to a different VT is possible and ssh login is not possible (no response on port 22). This happens both when booting with modesetting enabled, or when enabling mode-setting after a boot with radeon.modeset=0 and doing:

sudo /etc/init.d/gdm stop
sudo modprobe -r drm radeon
sudo modprobe radeon modeset=1
sudo /etc/init.d/gdm start

Any ssh session that is logged in at the time will stop responding.

When drm is loaded with debugging enabled, i.e.:
sudo /etc/init.d/gdm stop
sudo modprobe -r drm radeon
sudo modprobe drm debug=1
sudo modprobe radeon modeset=1
sudo /etc/init.d/gdm start

gdm does start and I can log into my session, however it changing the VT is not possible. Pressing e.g. ctrl-alt-f1, results in the mouse pointer disappearing but the screen display otherwise remains the same. It is possible to switch back to VT-8 and the mouse pointer reappears.

Once drm has be loaded with debugging, it can be removed and the first set of commands does work (over ssh), however switching VT remains impossible.

I've attached the kernel.log and Xorg.log and debug file for the case when drm debugging is enabled.
There's no log files for the case when the system locks up, there seems to be nothing written to the logs.

I hadn't tried the plain drivers on Lucid, but it might be useful for you to know that my HD4350 works very nicely on Maverick; it might be worth you trying it.

Jochen Schroeder, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

Unfortunately I do not own a PC with AMD card anymore, so I can't test.

Cheers
