** Description changed: Launching Firefox (from the KDE panel) sporadically causes a kernel Oops (Null pointer dereference) in drm_debugfs_remove_files (output is attached). The system continues to run, and after returning to the desktop session by switching away from the vt and back again, Firefox is actually running. EDIT: The bug appears since the upgrade to oneiric, both with Firefox 7 and now 8. $ lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 $ apt-cache policy xserver-xorg-video-nouveau xserver-xorg-video-nouveau: Installed: 1:0.0.16+git20110411+8378443-1 Candidate: 1:0.0.16+git20110411+8378443-1 Version table: *** 1:0.0.16+git20110411+8378443-1 0 500 http://de.archive.ubuntu.com/ubuntu/ oneiric/main i386 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: xserver-xorg-video-nouveau 1:0.0.16+git20110411+8378443-1 ProcVersionSignature: Ubuntu 3.0.0-13.22-generic-pae 3.0.6 Uname: Linux 3.0.0-13-generic-pae i686 ApportVersion: 1.23-0ubuntu4 Architecture: i386 Date: Tue Nov 29 20:09:59 2011 EcryptfsInUse: Yes ProcEnviron: LANGUAGE=en_US:en PATH=(custom, user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: xserver-xorg-video-nouveau UpgradeStatus: Upgraded to oneiric on 2011-10-13 (47 days ago) + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24. + AplayDevices: + **** List of PLAYBACK Hardware Devices **** + card 0: Intel [HDA Intel], device 0: ALC861-VD Analog [ALC861-VD Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + ApportVersion: 1.23-0ubuntu4 + Architecture: i386 + ArecordDevices: + **** List of CAPTURE Hardware Devices **** + card 0: Intel [HDA Intel], device 0: ALC861-VD Analog [ALC861-VD Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: marc 3980 F.... pulseaudio + CRDA: Error: [Errno 2] No such file or directory + Card0.Amixer.info: + Card hw:0 'Intel'/'HDA Intel at 0xfc300000 irq 47' + Mixer name : 'Realtek ALC861-VD' + Components : 'HDA:10ec0862,17aa3867,00100001' + Controls : 19 + Simple ctrls : 12 + DistroRelease: Ubuntu 11.10 + EcryptfsInUse: Yes + HibernationDevice: RESUME=UUID=79a83231-1718-4040-a4aa-0060c32fe112 + MachineType: LENOVO 0769AP2 + Package: linux (not installed) + ProcEnviron: + LANGUAGE=en_US:en + PATH=(custom, user) + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.0.0-13-generic-pae root=UUID=d5677094-c049-4df2-bbae-a8fac07758a1 ro pcie_aspm=force + ProcVersionSignature: Ubuntu 3.0.0-13.22-generic-pae 3.0.6 + RelatedPackageVersions: + linux-restricted-modules-3.0.0-13-generic-pae N/A + linux-backports-modules-3.0.0-13-generic-pae N/A + linux-firmware 1.60 + RfKill: + 0: phy0: Wireless LAN + Soft blocked: no + Hard blocked: no + Tags: oneiric + Uname: Linux 3.0.0-13-generic-pae i686 + UpgradeStatus: Upgraded to oneiric on 2011-10-13 (50 days ago) + UserGroups: adm admin audio backup cdrom dialout lpadmin plugdev rtkit sambashare subversion + WpaSupplicantLog: + + dmi.bios.date: 07/29/2008 + dmi.bios.vendor: LENOVO + dmi.bios.version: 68ET37WW + dmi.board.name: IEL10 + dmi.board.vendor: LENOVO + dmi.board.version: REFERENCE + dmi.chassis.asset.tag: No Asset Tag + dmi.chassis.type: 10 + dmi.chassis.vendor: No Enclosure + dmi.chassis.version: N/A + dmi.modalias: dmi:bvnLENOVO:bvr68ET37WW:bd07/29/2008:svnLENOVO:pn0769AP2:pvr3000N200:rvnLENOVO:rnIEL10:rvrREFERENCE:cvnNoEnclosure:ct10:cvrN/A: + dmi.product.name: 0769AP2 + dmi.product.version: 3000 N200 + dmi.sys.vendor: LENOVO ** Attachment added: "AcpiTables.txt" https://bugs.launchpad.net/bugs/897821/+attachment/2617959/+files/AcpiTables.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/897821 Title: Null pointer dereference in drm_debugfs_remove_files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/897821/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
