[Ubuntu-x-swat] [Bug 1111884]
I tried to fix this a few months ago but failed. If someone with the right skills and time want to have a look at this problem, I'd be happy to give away a laptop with this chipset. Shipment cost on me. I can prepare a linux installation with sources of the kernel at the regression point.

(In reply to comment #47) (In reply to comment #46) I tried to fix this a few months ago but failed. If someone with the right skills and time want to have a look at this problem, I'd be happy to give away a laptop with this chipset. Shipment cost on me. I can prepare a linux installation with sources of the kernel at the regression point. Contact me if you are up to the task. Don't do that. Read here: https://wiki.ubuntu.com/Kernel/KernelBisection If you can follow those Ubuntu-specific instructions, that will narrow down the problem. If you can't follow those instructions, have you filed a Launchpad bug? If so, please post the link or bug # (double-check that it's a public bug or say it's private). The problem is already bisected. The commit that introduces the regression switches nv50 to use nvc0's disp implementation. The commit is basically deleting all the nv50 code and changing a few function pointers to use the nvc0 implementation. I tried pin pointing what the problem was (see comment 34) but I was not able to fix the problem. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/884 Title: 10de:0611 nouveau fails at suspend/resume - PAGE_NOT_PRESENT To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/884/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I saw Ben Gamari's bisection log (from 3.7-3.8), but I didn't realize that you had duplicated the bisection; I only saw your bump 4 months later, on 3.13. The OP reported this for a Dell Latitude E6400 with G98; are you running similar hardware? HW is not identical. I have a Dell XPS 1330 with 8400M GS (10de:0427) I originially reported my problem in bug 62835. After bisection I found this issue with the same offending commit and identical symptom. Donation offer still valid. I have two of these machines laying around collecting dust. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/884 Title: 10de:0611 nouveau fails at suspend/resume - PAGE_NOT_PRESENT To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/884/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Some new observations made while investigating this issue: * Without X started suspend/resume works fine * With NoAccel set in xorg conf file suspend/resume works fine * If X is stopped before suspending the resume works ok but if I try to start X a second time after resume, X hangs. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/884 Title: nouveau fails at suspend/resume - PAGE_NOT_PRESENT To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/884/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

(In reply to comment #32) One idea I just randomly had was that there might be a difference in the teardown process. For example, in the removed code, nv50_display_fini did stuff. In the current code, it's basically empty (well, some small bits in nouveau_display_fini). It looks like the old code (a) blanked each crtc (b) sent out a EVO_UPDATE command (c) waited for each crtc to hit a vblank (d) did something with the cursor (cleared it?) (e) waited for some sort of DPMS thing It could well be that this now happens elsewhere, but I just wanted to put that thought down on paper. I tried this idea by doing the following: 1) Checked out 4f6029da58ba9204c98e33f4f3737fe085c87a6f^1 (= f9887d091149406de5c8b388f7e0bb6932dd621b) 2) Deleted everything in nv50_display_fini With that change suspend/resume works so I guess the problem is elsewhere. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/884 Title: nouveau fails at suspend/resume - PAGE_NOT_PRESENT To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/884/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
