On Lenovo g570 ubuntu 12.10 worked perfectly. After upgrade to 13.04 X-Windows started locking up (only the mouse cursor was reacting to mouse movements, but nothing else). The lockup occurs after couple of minutes working in gnome-classic-fallback window manager, no 3D activity was done at the time (at least intentionally). The X lockup is accompanied by messages like these in dmesg (every second or so): [ 533.963858] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... render ring idle [waiting on 25899, at 25898], missed IRQ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761065 Title: [Sandybridge] Spurious *ERROR* Hangcheck timer elapsed... blt ring idle messages in dmesg when using compiz To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/761065/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed: + SRU Justification: + Fixes a constant stream of hangcheck errors flooding dmesg, and + removes the visible stuttering that was caused by it when using 3D + applications. + Impact: + Fixes missed interrupts on sandybridge GPU's. It doesn't affect any + other GPU generation. + Fix: + Upstream commit 498e720b96379d8ee9c294950a01534a73defcf3. + Testcase: + 1) Install mesa-utils on a system using sandybridge graphics on 11.04 + 2) run vblank_mode=0 glxgears and let it run for 30 seconds or so + 3) kill it then check dmesg + 4) Without fix: hangcheck messages every ~5 seconds, massive + stuttering of the whole desktop observed. With fix: no hangcheck + messages, able to continue using the desktop. + + This was sent to stable, but 2.6.38.y stable is dead so it will need + to be manually cherry-picked. It has been tested extensively locally + as well as by users on the bug whom I provided test kernels for. It + applies cleanly to ubuntu-natty.git. + + + Original bug: + - Binary package hint: xserver-xorg-video-intel When using unity or a Ubuntu classic session with compiz, there are spurious [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 9004, at 9004], missed IRQ? visible in dmesg. The display stops updating for a fraction of a second when it happens. This can be forcibly reproduced by doing vblank_mode=0 glxgears with compiz active and it is specific to sandybridge systems. Disabling sync to vblank in compiz doesn't have any effect, and the problem does not happen when using metacity.

I'm using Ubuntu Oneiric with the 3.0 kernel in the repositories and the entire X stack from the xorg-edgers PPA.

i'm having similar issues...and it most certainly seems to be originating from the kernel and not from the X server, as i've run through three different versions of both the kernel and the X server while holding one fixed and changing the other and changing the X server didn't affect the problem at all, but changing the kernels did. not sure what debugging information might be helpful in helping to shed light on my particular config, but would be happy to post some, just let me know what to post. for now, i'll just attach an lspci and give a bit of a description: (1) started with latest version of ubuntu iso on thinkpad x220 with corei7-2620m and intel HD3000. the iso at the time provided me with kernel and headers version 2.6.38-8.42. aside from some thinkpad- tinkering, everything pretty much worked out of the box, as others have reported. (2) then, connected to dell u2711 via displayport and got a desktop that was seemingly split between two windows, and everything on the u2711 was blacked out except for the top menu and a square sitting on the lower left corner of the panel the size of the thinkpad's display. thinkpad display unresponsive during this time (but not black). rebooted with display connected and both screens black (and unusable). (3) tried to upgrade to kernel 2.6.39-1.6, which had the same outcome as kernel 2.6.39-2.7. upon reboot, monitors set to mirror same image with 1024x768 resolution. i know this is unrelated, but here and with the 2.6.38-8.42 kernel, the Fn-F7 worked for switching between resolutions. anyway, upon switching between resolutions i got the same outcome as in (2), except that now i could use the Fn-F7 to switch between non-working full-resolutions and working (mirrored) 1024x768 resolutions. (4) after a bit of digging around, found a recommendation to try kernel 2.6.38-996-generic #201103251543 SMP Fri Mar 25 15:47:37 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux, and accompanying headers, which worked properly. currently using xorg-server 2:1.10.1+git20110429+server-1.10-branch.b4455b11-0ubuntu0sarvatt, but switching to 2.14.0ubuntu7.1 from the natty updates, as well as using 2.14-0-4ubuntu7 (natty) made absolutely no difference. these three xorg versions were used in all my testing. At (4) both displays are function properly. however, i cannot switch between monitors without rebooting. whatever monitor i boot in works, but if that's the u2711 fed through the display port, then if i unplug the display port cable, the thinkpad LCD is not switched to automatically (and remains off, not just black). likewise, if i boot with the thinkpad display active, plugging in the u2711 9-times-out- of-10 causes both screens to go black, the Fn-F7 doesn't work, and to fix the problem i have to hard-reboot. it's interesting to note that in the gnome monitors panel, only the active display shows. in other words, if i boot while connected to the u2711, it shows (but the built-in laptop screen doesn't), and if i boot without the external display connected, the thinkpad LCD shows, but once i plug in the u2711 (without rebooting) the 1 time out of 10 the display doesn't go nuts on me, it only shows the u2711 and not both the u2711 and the thinkpad LCD, as i would expect. a strange aside, the thinkvantage button works for every kernel change except (4), the one in which both displays work properly. additionally, i had to recompile the r8192ce_pci wireless module from the DKMS package to get it to work with each kernel change as this driver was not included in the newer kernels. ** Attachment added: lspci.output https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/761065/+attachment/2134357/+files/lspci.output -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761065 Title: [Sandybridge] Spurious *ERROR* Hangcheck timer elapsed... blt ring idle messages in dmesg when using compiz -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@AceLan Kao I think I found the i915 patch, which would fix this bug (along with a lot of other documented i915 fixes): from (http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.39-rc1) commit 36d527deadf7d0c302e3452dde39465e74a65a08 Author: Chris Wilson ch...@chris-wilson.co.uk Date: Sat Mar 19 22:26:49 2011 + drm/i915: Restore missing command flush before interrupt on BLT ring We always skipped flushing the BLT ring if the request flush did not include the RENDER domain. However, this neglects that we try to flush the COMMAND domain after every batch and before the breadcrumb interrupt (to make sure the batch is indeed completed prior to the interrupt firing and so insuring CPU coherency). As a result of the missing flush, incoherency did indeed creep in, most notable when using lots of command buffers and so potentially rewritting an active command buffer (i.e. the GPU was still executing from it even though the following interrupt had already fired and the request/buffer retired). As all ring-flush routines now have the same preconditions, de-duplicate and move those checks up into i915_gem_flush_ring(). Fixes gem_linear_blit.

On my setup (Dell 6420 with integrated HD3000; shows as 8086:0126 (rev 09) in lspci; running Debian 2.6.38-2), the bug appears only after a while (so it's hard to reproduce).

I will stick with this kernel until the bug happens again (or not ;-)) Just tried neverball for a couple of minutes, it didn't trigger the bug. Note: I don't know if it's relevant, but since I installed this kernel, opening the lid of the laptop will turn the screen to black. The screen remains OK when I close the lid, but when I re-open it, it goes black. It's not off (I still see the backlight), just black. It is then stuck in that state: switching back to textmode won't help. However, if I suspend to RAM and resume, the screen will work again. Before using this kernel, this bug occured exactly 50% of the time (i.e., I could close+open once, and the 2nd time would trigger the bug). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761065 Title: [Sandybridge] Spurious *ERROR* Hangcheck timer elapsed... blt ring idle messages in dmesg when using compiz -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
