<p>Is there another place to report this kind of issue? Didn't get any feedback. Did I make mistakes in my mail? I already tried the Ubuntu bug-tracker (see below) with no success.<o:p></o:p></p>
<p>Thank you,<o:p></o:p></p>

<p>but guys from Ubuntu seems not able to help (as it is an upstream bug) !?<o:p></o:p></p>
<p>This happend not in older kernels, but these have the problem not to go in power save states. So I think the fix of that <o:p></o:p></p>

<p>causes this regression. <o:p></o:p></p>
<p>Hope someone can help. For a laptop it is better to have both - standby and power saving. Thank you.<o:p></o:p></p>
