[Ubuntu-x-swat] [Bug 1081009]
Hi everyone, (In reply to comment #129) (In reply to comment #126) Ok. seems to work very stable now. I am running now a few days with the patches xf86-intel driver and this patch (#122), and didn't have any hiccups at all. Ok, I got one. It took a *long* time, and I (stupidly) didn't grab the error state (too tired after 24 hours of flight/travel), but it definitely happened while running a apt-get upgrade after a long time, while at the same time browsing photos from my travel. Let's say, the situation as wastely improved, but is not perfect. I will try to get the error state as soon as I hit it again. Actually trying it over, I see the following: 3.7.0 plus patch from #122 with patched intel driver is rock solid 3.8.0-rc2 with patched intel driver (but no kernel patch) hangs (uploading the error state file soon) I will try 3.8.0-rc3 with #122 patch plus the two from Chris 130/131 now.

3.7.0 plus patch from #122 with patched intel driver is rock solid 3.8.0-rc2 with patched intel driver (but no kernel patch) hangs (uploading the error state file soon) I will try 3.8.0-rc3 with #122 patch plus the two from Chris 130/131 now. 3.8.0-rc3 with patches from #122, #130, #131 seems to be very stable again. Concerning the other two requests: Since testing on *absence* of the bug always takes me a few days until I am convinced that it does not appear, which of the two #134 or #135 should I try next, taking into account that the patches from 122,130,131 do work out in some way.

Hi Daniel, hi Chris (In reply to comment #107) Created attachment 71805 [details] [review] make the shrinker less aggressive Duct-tape solution if it is one, but imo very much worth a try. There have been a lot of patches floating around, but I was running 3.7.0 plus this patch now for a while, and using UXA (*not* using SNA, with SNA it always was fine). I did not hit any problem till now, although I did heavy IO stuff as usual (svn up and git svn rebase on two 6+Gb repos), etc. Chris: What should I do next? You have posted two patches (108 and 109 comments), should I try both, or each on independently? Or is the information that patch from 107 is fine (till now) enough? Please let me know, and thanks for your work on that, and Merry Christmas!

(In reply to comment #115) (In reply to comment #114) Yes, it is xf86-video-intel. I am running it with the current version of Debian/sid + this patch now (2.20.14-1 + the patch) Is it a standalone patch or does it depend on the former DRM patch? Anyway, I have tested it with 3.7.1 + i915.i915_enable_rc6=1 and it still triggers the hang check thingey as before. (without enabling rc6 it does not do that) the rc6 needs to be disabled *in*any*case*, that is known by now. And it is a standalone patch of xf86-video-intel. Did you recompile it? [reply to comment 111] I tried to apply https://patchwork.kernel.org/patch/1896161/ on top of vanilla v3.7.1, but I could not get it to compile: Hmm, I have compiled it with 3.7.0 git kernel without a problem, some offset while patching but that was all. I got some offset issues too, but it failed to compile at all because the function was not defined. Did you really apply the patch to the right source tree? Huuu? Are you sure? I checked my git commit log and it is kernel 3.7 tag of Linus, then the merge into my git repo, and then the patch. Nothing else. I guess you are running something else.

Hi Chris, (In reply to comment #90) (In reply to comment #89) First report on SNA: I got a very very strange thing yesterday. After resuming from suspend-to-ram I continued working with GIMP on some graphics, and first it started with some blue flashes on the screen, and finally the screen got completely blue, but I could in principle still interact with the windows, just without seeing anything. Interesting, certainly the first I've heard of such. Can you see if it is possible to capture it in a screenshot, or failing that a photograph, and please open a bug report for it. sorry for the late reply, I was on a trip. Since it only happened once and on some rc kernels I leave it for now, but a screenshot is not necessary, it was simply monocolor blue ... nothing else ;-) Another thing: I have now tried to hit the bug with SNA for a long time, without *any* success. As soon as I switched back to IXA the bug was triggered within short time. Does this help you?

Hi Chris, I am now running with http://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=for-imre pulled into main linux git.

Okay, I guess I have to recall my statement, I didn't realize it at first. Due to the i915.enable_hangcheck=0 it seemss that not simply the 3d died and Gnome3 WM died, but with this the screen went black and didn't react on anything. Interestingly there were no messages at all in the log files. I could SysRq the computer, and the logfiles showed activity, but the screen remain black. I guess that is the sign of a hang.
