[Bug 1488719] Re: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"
I'm still not sure what we're looking at here, especially if the original message this bug deals with has anything to do with the other described buggy behaviour here, which are: random freezes, display flickering, not working external displays etc. I watched the development of the comments in this bug really closely (not at least because of my own interests being affected as well) and there hasn't been any real progress in investigating this issue(s) further. I think this is not least caused by the complexity and variatons of issues regarding graphics. IMHO this leads to three taks which has to be done: 1. Identifiying distinct issues and filing distinct bug reports while being aware of possible duplicates. 2. If you're affected and feeling confident in providing more information, investigate those distinct issues further and provide proper amounts of logs/traces etc. possbile related to those distinct issues. 3. Pushing those issues to the proper upstream bugtrackes. (For me this is one of the hardest parts, since I'm not sure which parts play a role here, e.g. kernel, display manager etc.) When I look at my own logs (attached) my issue still looks like a kernel problem. I've tested the 4.5RC7, the origial message is gone, but my external display (connected to DP of my advanced lenovo dock) stays black if the T450s is docked while booting. If I undock after boot and then dock it again, the system freezes totally and syslog is showing some serious kernel issues. The only way to cirumvent this behaviour is to boot undocked and then dock when the system is fully booted. I'm currently using this workaround in my daily work to see if there are other issues. I think I will file a bug report on bugs.freedesktop.org later. ** Attachment added: "Syslog portion from plugging to dock until crash" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1488719/+attachment/4595095/+files/syslog.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488719 Title: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"

Yes this patch is in the mainline kernel v4.5-rc1-wily. But I think regarding our problem here it does only what it says: shut up the messages. I just tested it, got a [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun at boot time now (related: https://bugzilla.kernel.org/show_bug.cgi?id=95461), while the [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)! are gone. With external monitor connected things getting worse, gdm isn't able to use the monitor correctly and crashes from time to time. Looks like there are now other i915 bugs (maybe regression?) more urgent. Personally I will stick to 4.4 until I've got time to investigate this further with a clean install of ubuntu to eliminate the possibility that I'm looking at completely unrelated issues here. ** Bug watch added: Linux Kernel Bug Tracker #95461 http://bugzilla.kernel.org/show_bug.cgi?id=95461 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488719 Title: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"

I have to revice my comment from January 4th. The error is gone without external display connected with 4.4.0 rc7 for me too, still occuring with ext. display connected. I'm not sure what I was looking at, maybe booted the wrong kernel, stupid me. Since yesterday 4.4.0 rc8 is released, same behaviour without external display connected, error is gone. I will check rc8 with external display connected later this day when I'm at home. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488719 Title: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"

@joakimkoed Yes this seems to be an upstream issue, see (updated) related freedesktop bug above, with no (working) fix released yet.

Maybe I don't get it, but: Is the fix only shutting up the kernel messages or is this fixing the cause? I'm expiriencing this messages on a Lenovo T450 (20BX011GE) running 15.10 with 4.2.0-16-generic kernel. I see this messages wether external monitor is connected or not, although with much higher frequency with external monitor connected (dp via dock). It seems like this messages is related to random GDM crashes. I tried to reproduce this behaviour, but I've got no clue when this is happening so far. I will try to investigate this further. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488719 Title: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"

I can confirm that the solution from #56 solves the problem with the dm- crypt password on boot, but there seem to be issues left. Still a lot of [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! in the kernel log. No system freezes so far, but I've only tested this for a few minutes.

[Bug 1500751] Re: Cryptsetup Keyboard not working on Xubuntu 3.19.0-30
I can confirm that 3.19.0-31-generic #36~RevertsV2 works without any of the issues. @rolfinator (seb2): Yes I have the same issues with the 3.19.0-30 kernel stated in the initial post (plus some random system freezes, except the workaround "boot -> wait for dm-crypt passphrase, which can't be entered --> reboot --> enter passphrase" works on 3.19.0-30, but system freezes remain afterwards). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1500751 Title: Cryptsetup Keyboard not working on Xubuntu 3.19.0-30 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1500751/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1500751] Re: Cryptsetup Keyboard not working on Xubuntu 3.19.0-30
The kernel from comment #46 didn't resolves the bug. The issue remains and even the reboot-workaround don't do the trick. When I disable splash then I can enter the passphrase, but afterwards the boot hangs with the kernel-log repeatedly stating [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! So it's almost the same behaviour as with the 3.19.0-30 kernel.

I can confirm this behaviour for my T450s runnig 15.04 with 3.19.0-30 kernel. Using the same workaround to input my dm-crypt password.
