nouveau pegs cpu on Sony Vaio VGN-Z890

[Simon Barber]

Using 12.04 rc2 on a Sony Vaio VGN-Z890 the CPU is pegged immediately when X is started, and then any keyboard activity freezes the machine. There is a exception in nouveau, and removing nouveau from the /lib/modules works around the problem.

(Sony has both Intel and Nvidia graphics).

Simon Barber, 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.
