dmesg log

the lcd screen of the laptop remains off after resume... the external display
comes on as expected...
Linux abbaton.ucd.ie 3.7.0-rc6-5-desktop #1 SMP PREEMPT Tue Nov 27 14:10:39 UTC
2012 (f8c5dde) x86_64 x86_64 x86_64 GNU/Linux


I have attached the dmesg log.


other funny things...
*if I start only with the lcd... kde would not start just freeze before plasma
being loaded ( probably another bug to be reported.)
* I have a last good commit and first bad commit from an older version of the
nouveau git
last good

I was trying to bisect but because of the 3.7 rebase I am lost... sorry
