apport information ** Description changed:
Binary package hint: xorg I have a rather old machine running a MythTV backend using a WinTV NOVA T USB2 (93000 Rev B8A2) and it seems that randomly the system will lock up completely. I have done my best to work out if the freeze occurs when recording or performing some function of the mythtv-backend but based on the logs it seems that it can occur during a recording, during a database update or when there is no activity at all. I do have BOINC installed and running but disabling that so it does not run at startup didn't seem to stop the problem; as the freeze occurs randomly every few days I had to wait about a week but the system did lock up without BOINC running at all. My next fiddle was to change the priority of the mythtvbackend process to be -3; this seemed to reduce the frequency of the freeze occurring but it may have been psychological as the occurance rate is so drawn out anyway. One thing which triggered a freeze was using the ubuntu-bug program, before the report that I am using to make this bug entry the system froze while ubuntu-bug was off collecting information about the problem. Again the mythtvbackend was running so I cannot discount this just being coincidence. Another symptom, which may just be how the thing works, is that the NOVA T USB2 strays in "warm" mode during the crash and if I use the PC's reset button to restart the system. When the system comes up like this the NOVA T is unresponsive and the red light on the from of it remains lit. If I power down the machine or pull the USB cord out from the NOVA T then plug it back in after several seconds while the bios boot splash screen is going then the red LED extinguishes and the device works fine once Ubuntu has booted. This is all a little scattered and probably unhelpful but I have tried to hunt down answers to this problem myself and have run out of ideas what to do next. Please do let me know if there are any further diagnostics that may be helpful. lsb_release -rd Description: Ubuntu 10.04.1 LTS Release: 10.04 ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: xorg 1:7.5+5ubuntu1 ProcVersionSignature: Ubuntu 2.6.32-28.55-generic 2.6.32.27+drm33.12 Uname: Linux 2.6.32-28-generic i686 NonfreeKernelModules: nvidia Architecture: i386 CheckboxSubmission: 5d0602330b5d44cd5ded7b4846756bb0 CheckboxSystem: daed2f3d6643b4a84b4520a2427f8c2b Date: Sat Feb 5 08:45:59 2011 InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Release i386 (20091028.5) ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.32-28-generic root=UUID=f8cbb2f7-5b7c-46db-94bc-1802d312a175 ro quiet splash ProcEnviron: LANG=en_GB.utf8 SHELL=/bin/bash SourcePackage: xorg Symptom: display Title: Xorg freeze dmi.bios.date: 08/16/2004 dmi.bios.vendor: Phoenix Technologies, LTD dmi.bios.version: 6.00 PG dmi.board.name: MS-6570E dmi.board.vendor: MICRO-STAR INTERNATIONAL CO., LTD dmi.chassis.type: 3 dmi.modalias: dmi:bvnPhoenixTechnologies,LTD:bvr6.00PG:bd08/16/2004:svn:pn:pvr:rvnMICRO-STARINTERNATIONALCO.,LTD:rnMS-6570E:rvr:cvn:ct3:cvr: system: distro: Ubuntu codename: lucid architecture: i686 kernel: 2.6.32-28-generic --- Architecture: i386 CheckboxSubmission: 5d0602330b5d44cd5ded7b4846756bb0 CheckboxSystem: daed2f3d6643b4a84b4520a2427f8c2b CurrentDmesg: [ 26.607216] agpgart-nvidia 0000:00:00.0: AGP 3.0 bridge [ 26.607241] agpgart-nvidia 0000:00:00.0: putting AGP V3 device into 8x mode [ 26.607326] nvidia 0000:01:00.0: putting AGP V3 device into 8x mode [ 29.232041] eth0: no IPv6 routers present [ 104.758599] ondemand governor failed, too long transition latency of HW, fallback to performance governor DistroRelease: Ubuntu 10.04 InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Release i386 (20091028.5) NonfreeKernelModules: nvidia Package: nvidia-graphics-drivers-173 (not installed) ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.32-28-generic root=UUID=f8cbb2f7-5b7c-46db-94bc-1802d312a175 ro quiet splash ProcEnviron: LANG=en_GB.utf8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.32-28.55-generic 2.6.32.27+drm33.12 Tags: lucid lucid Uname: Linux 2.6.32-28-generic i686 UserGroups: adm admin cdrom dialout lpadmin mythtv plugdev sambashare dmi.bios.date: 08/16/2004 dmi.bios.vendor: Phoenix Technologies, LTD dmi.bios.version: 6.00 PG dmi.board.name: MS-6570E dmi.board.vendor: MICRO-STAR INTERNATIONAL CO., LTD dmi.chassis.type: 3 dmi.modalias: dmi:bvnPhoenixTechnologies,LTD:bvr6.00PG:bd08/16/2004:svn:pn:pvr:rvnMICRO-STARINTERNATIONALCO.,LTD:rnMS-6570E:rvr:cvn:ct3:cvr: system: distro: Ubuntu codename: lucid architecture: i686 kernel: 2.6.32-28-generic + --- + Architecture: i386 + CheckboxSubmission: 5d0602330b5d44cd5ded7b4846756bb0 + CheckboxSystem: daed2f3d6643b4a84b4520a2427f8c2b + DistroRelease: Ubuntu 10.04 + InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Release i386 (20091028.5) + NonfreeKernelModules: nvidia + Package: nvidia-graphics-drivers-173 (not installed) + ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.32-28-generic root=UUID=f8cbb2f7-5b7c-46db-94bc-1802d312a175 ro quiet splash + ProcEnviron: + LANG=en_GB.utf8 + SHELL=/bin/bash + ProcVersionSignature: Ubuntu 2.6.32-28.55-generic 2.6.32.27+drm33.12 + Tags: lucid lucid + Uname: Linux 2.6.32-28-generic i686 + UserGroups: adm admin cdrom dialout lpadmin mythtv plugdev sambashare + dmi.bios.date: 08/16/2004 + dmi.bios.vendor: Phoenix Technologies, LTD + dmi.bios.version: 6.00 PG + dmi.board.name: MS-6570E + dmi.board.vendor: MICRO-STAR INTERNATIONAL CO., LTD + dmi.chassis.type: 3 + dmi.modalias: dmi:bvnPhoenixTechnologies,LTD:bvr6.00PG:bd08/16/2004:svn:pn:pvr:rvnMICRO-STARINTERNATIONALCO.,LTD:rnMS-6570E:rvr:cvn:ct3:cvr: + system: + distro: Ubuntu + codename: lucid + architecture: i686 + kernel: 2.6.32-28-generic ** Attachment added: "BootDmesg.txt" https://bugs.edge.launchpad.net/bugs/713551/+attachment/1855611/+files/BootDmesg.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-173 in ubuntu. https://bugs.launchpad.net/bugs/713551 Title: Xorg freeze; system locks and accepts no input, keyboard lights go out when key is touched _______________________________________________ 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
