Not sure if my bug belongs as part of #507504 or #555573 - posting it both places. I can reproduce the 'Hangcheck timer elapsed... GPU hung' message and crash easily and reliably. also getting the .. drm:i915_gem_idle] *ERROR* hardware wedged messages in the kern.log file Environment : fresh install of 10.04 LTS, intel 915 video.
To make the crash happen : Go to system->preferences->screen saver and select 'ant spotlight' or 'GL Slideshow'. This PC will crash within 3 seconds reliably, over& over, as many times as I try. To make crashes much less frequent : Same menu, quickly before the ant starts revolving, select 'gl matrix' Floating Ubuntu or hyper-torus for the saver. Crashes will still happen, just not constantly anyway, an easy reproducable way to cause a crash may be helpful to somebody. lspci says : lspci 00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 01) 00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01) 00:1d.0 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 81) 00:1f.0 ISA bridge: Intel Corporation 82801DB/DBL (ICH4/ICH4-L) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801DB (ICH4) IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus Controller (rev 01) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) 05:08.0 Ethernet controller: Intel Corporation 82801DB PRO/100 VM (LOM) Ethernet Controller (rev 81) uname -a says : Linux pete-desktop 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 22:02:19 UTC 2010 i686 GNU/Linux -- [g41] GPU hung: Failed to submit batchbuffer: Input/output error https://bugs.launchpad.net/bugs/555573 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ 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
