Comment 4 Olivier Jaulent 2011-02-20 08:09:28 UTC

I'm on a laptop (MSI) and the behaviour for me is a freeze every 10 seconds.
This happen only when my external screen is plugged, I do not have to use it, just plug it and the bug appear. If I unplug it the bud disappear.

I'm using hdmi connectivity.

I found similar bugs on internet (first one from Linus Torvald):

I'm under Ubuntu Natty (Alpha) :

Comment 5 Olivier Jaulent 2012-01-31 06:42:34 UTC

Problem solved ! Nouveau is not the root cause. Kernel is.

Workaround can be found here : http://souriguha.wordpress.com/2011/03/08/how-to-solve-problem-with-thinkpadkslowd-kworker-on-linux-kernel-2-35-2-36/

To solve until next reboot (as root): 
echo N> /sys/module/drm_kms_helper/parameters/poll

To solve definitely (as root) :
echo "options drm_kms_helper poll=N">/etc/modprobe.d/local.conf
