Nouveau driver doesn't work for NV34 on AMD Irongate based system

[Clemens Eisserer]

On an AMD-751 chipset based system (AMD Irongate) the nouveau kernel-module fails to initialize printing some backtraces, like:

May 14 19:17:28 max-desktop kernel: [ 3.746994] [<c014c3d2>] warn_slowpath_common+0x72/0xa0

Sorry forgot to mention, this happens with a fresh Ubuntu-10.04 installation

Anything I could do to help diagnose the problem?
E.g. is it possible to switch back to PCI mode, like it can be done with the oss radeon driver?

Clemens Eisserer, 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-nouveau 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.
