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
http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=f4a75d2eb7b1e2206094b901be09adb31ba63681
first bad
http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=9677f3d63de8f87d8e18a5509c8b18eed468e379

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

I have tested with 3.8rc2 both default driver and 3.8rc2 with the nouveau
master compiled... both show the same behaviour as described above.
The 3.7.1 kernel with the driver that comes works...but fills my log with
trapped read and write errors.

I have tried the patch suggested in bug 59057 but the same situation...
I have attached the log for it with the debug activated.

Hi Marcin,

unless I do something very silly I did not manage to compile the two commits
indicated against 3.8rc2
Here what I have done

git clone --depth 0 git://anongit.freedesktop.org/nouveau/linux-2.6 nouveau
cd nouveau
git checkout 186ecad21

extracted the needed folders and compiled... 
got the error...
