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
Comment 1 Alin M Elena 2013-01-07 19:16:09 UTC
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.

Comment 2 Marcin Slusarz 2013-01-07 19:29:46 UTC
Probably connected: bug 59057, bug 58729.
Comment 3 Alin M Elena 2013-01-07 20:14:02 UTC
I have tried the patch suggested in bug 59057 but the same situation...
I have attached the log for it with the debug activated.

Comment 5 Marcin Slusarz 2013-01-07 21:41:02 UTC
Please verify 186ecad21 is the first bad commit (boot 186ecad21 and 4a230fa618).

Hi Marcin,

I will give it a try sometime tomorrow.

Comment 7 Alin M Elena 2013-01-08 13:06:41 UTC
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...

I will mark is as duplicate of 59057 as it seems to have more comments
