It's now a big lottery to 'suspend/resume' my Lenovo T61 GMA965 - this problem is quite longterm - it happened from time to time in the past, but disabling drm_kms_helper thread seemed to minimize it. However now with kernel 2.6.39-rcX - it strikes back with full power - nothing seems to help - and it's like 1 from 3-4 resumes ends with plasma effect on resume - when this happens - the only way to have the laptop usable is to make a full reboot - machine seems to work OK - but without display it's not really useful. I'm attaching phone video grab of such plasma effect. Recently there are some extra warnings in the message log - but they are probably unrelated to real cause - they are just side effect - when I tried after such broken resume to suspend machine again. So here is the log from 'resume -> (plasma) -> suspend -> resume...' Freezing user space processes ... (elapsed 0.01 seconds) done. Freezing remaining freezable tasks ...

Created attachment 45368 [details] Plasma effect on Intel display during resume
Might be an underrun, but looks more like an incorrect pageflip. The last bug purporting to be a pageflip issue with KDE was bug 32303 and was fixed by http://lists.x.org/archives/xorg-devel/2010-December/016511.html.
As more information could be helpful here - I'm using kernel build with a lot of debug stuff enabled - so maybe it could be some timing issue. I've today tried to debug this with serial console and with drm.debug=0xe - but instead I got couple USB errors ;) - but no plasma - so it looks really something with timings. Also - I'm switching to console and running manually pm-suspend - to avoid any clash with 'Xserver' (as running rawhide is sometime a problem) So I get this 'plasma' even when I'm just on console. Also running rawhide means: xorg-x11-server-Xorg-1.10.0-7.fc15.x86_64 And drm & intel driver are taken from git repositories - and they are uptodate. But as I said - I've seen this plasma even in past - so it's not a new problem from this week - but I don't remember where it has started :( Anyway - it's not so easy debug it - as there is no 'straight' way to trigger it. I'll try to collect GPU dump when this happens.
Created attachment 45465 [details] dmesg from undock I've started to play a bit more with 'undocking' mechanism used in my T61. As there are couple other weird things going on when try to play with this stuff a bit more. In the attached file - you may find couple message like: [30034.339914] [drm:i915_pageflip_stall_check], Pageflip stall detected Maybe these thing could be related to this problem ? (Thought for now I'm NOT able to get the plasma effect on resume) Also - why is the CRT being detected twice ?
Ok - today I've got another plasma - I've trie to grab some more info - though I've missed probably few important parts (next time I'll do better - if current info wouldn't be enough) So first - here is the messsage log (unfortunately without debug log :( ) Timing info is left in - the problem might be related to very 'quick' resume after suspend - while the lid is kept closed.

Seeing that assert_pipe again reminded me of: commit f6e5b1603b8bb7131b6778d0d4e2e5dda120a379 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Apr 12 18:06:51 2011 +0100 drm/i915: Sanitize the output registers after resume Similar to booting, we need to inspect the state left by the BIOS and remove any conflicting bits before we take over. The example reported by Seth Forshee is very similar to the bug we encountered with the state left by grub2, that the crtc pipe<->planning mapping was reversed from our expectations and so we failed to turn off the outputs when booting or, in this case, resuming. This may be in fact the same bug, but triggered at resume time. This patch rearranges the code we already have to clear up the conflicting state upon init and calls it from reset (which is called after we have lost control of the hardware, i.e. along both the boot and resume paths) instead. Though I didn't expect 965GM to be affected by that bug. Can you please test that patch (on drm-intel-fixes) and see if it is in fact the same bug?
> Though I didn't expect 965GM to be affected by that bug. Can you please test > that patch (on drm-intel-fixes) and see if it is in fact the same bug? So taking this one: http://git.kernel.org/?p=linux/kernel/git/ickle/drm-intel.git;a=commitdiff;h=f6e5b1603b8bb7131b6778d0d4e2e5dda120a379 But do I need to change anything for 965GM ? Also note I'm not able to trigger this bug easily - though I could enable drm_kms_helper thread which seemed to bring this problem more often. I'll keep running my laptop for a few days to see whether I'll hit this problem again.
It'll work (or not) as is for 965GM. /me crosses his fingers that this is the answer.

Another user with similar laptop does not experience these troubles - thought I'm seeing the plasma effect for quite some time. Anyway it would be good to see it finally fixed before I get a new one ;) Anyway: dmidecode about my T61 bios: BIOS Information Vendor: LENOVO Version: 7LETC7WW (2.27 ) Release Date: 04/08/2010 And here is the one - which 'might not' be giving troubles: BIOS Information Vendor: LENOVO Version: 7LETC5WW (2.25 ) Release Date: 11/14/2008
Ok - I really start to feel you've really hit the nail on the head - I've not seen the plasma problem from that day - so you could probably close it as a duplicate of your already fixed bug for other chipset (if there is other Xorg bug except the Ubuntu one).
Created attachment 45926 [details] pipe assert Ok - my display seems to be fine so far - i.e. no plasma effect. But I'm still getting those warnings logged occasionally during suspend/resume
Sad news today - plasma strikes back - my actual kernel is past 2.6.39-rc6 - so it has your sanitize patch already included upstream. I'll try to collect few more info about this state. Then I'll make a reboot. WARNING: at drivers/gpu/drm/i915/intel_display.c:1203 assert_pipe+0x75/0x80 [i915]() Is present in dmesg log - seems like the problem happens during suspend?

Created attachment 48229 [details] trace of intel lock Here is quite similar error which happened today - with my rawhide - after like 3 minutes from running xlock. So it seems like the error could be triggered even without suspend. This is mostly plain 2.6.39 kernel with few minor local patches (dm related) xorg-x11-drv-intel-2.15.0-4.fc16.x86_64 xorg-x11-server-Xorg-1.10.99.1-6.20110510.fc16.x86_64 Unfortunately I've had remote access to this machine in the moment of crash. I'll eventually try later to trigger same conditions to grab same more error info.
A patch referencing this bug report has been merged in Linux v3.0-rc1: commit 2c7111dbaec72b01c804afb8ad77c6c7523986fd Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Mar 29 10:40:27 2011 +0100 drm/i915: Disable all outputs early, before KMS takeover
Hoping this isn't an issue anymore, but it would be good to get confirmation. Zdenek?
