+++ This bug was initially created as a clone of Bug #23664 +++ Forwarding this bug from Ubuntu reporter Neil Wilson: http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/419434 [Problem] X server fails with DRI : drmRadeonCmdBuffer: -22 [Original Description] Latest update to Karmic busts the GNOME session. I see the new xsplash graphic. The cursor changes to waiting for a bit and then I'm back to the GDM login window. It looks like Xorg died: gnome-settings-daemon: Fatal IO error 104 (Connection reset by peer) on X server :0.0. gnome-session: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0. ----- The application 'gnome-panel' lost its connection to the display :0.0; most likely the X server was shut down or you killed/destroyed the application. XIO: fatal IO error 0 (Success) on X server ":0.0" after 1159 requests (1152 known processed) with 0 events remaining. No protocol specified Window manager error: Unable to open X display :0.0 The key issue is drmRadeonCmdBuffer: -22 After which the X server fails. However it loads the GDM OK and will load the xterm default succesfully. Switching off DRI on RADEONHD and ATI allows the full gnome session to load properly. ----- Architecture: amd64 DistroRelease: Ubuntu 9.10 Lsusb: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub MachineType: Acer Aspire 5536 Package: xserver-xorg-video-ati 1:6.12.99+git20090629.f39cafc5-0ubuntu6 PackageArchitecture: amd64 PccardctlIdent: PccardctlStatus: ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.31-8-generic root=UUID=e544e0c3-bb61-4527-9393-26be9e351588 ro quiet splash ProcEnviron: PATH=(custom, no user) LANG=en_GB.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.31-8.28-generic RelatedPackageVersions: xserver-xorg 1:7.4+3ubuntu5 libgl1-mesa-glx 7.6.0~git20090817.7c422387-0ubuntu3 libdrm2 2.4.12+git20090801.45078630-0ubuntu1 xserver-xorg-video-intel 2:2.8.1-1ubuntu1 xserver-xorg-video-ati 1:6.12.99+git20090629.f39cafc5-0ubuntu6 Uname: Linux 2.6.31-8-generic x86_64 UserGroups: libvirtd XorgConf: Error: [Errno 2] No such file or directory: '/etc/X11/xorg.conf' dmi.bios.date: 02/27/2009 dmi.bios.vendor: Phoenix Technologies LTD dmi.bios.version: V1.03 dmi.board.name: JV50PU dmi.board.vendor: Acer dmi.board.version: Rev dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: N/A dmi.modalias: dmi:bvnPhoenixTechnologiesLTD:bvrV1.03:bd02/27/2009:svnAcer:pnAspire5536:pvr0100:rvnAcer:rnJV50PU:rvrRev:cvnAcer:ct10:cvrN/A: dmi.product.name: Aspire 5536 dmi.product.version: 0100 dmi.sys.vendor: Acer fglrx: Not loaded system: distro: Ubuntu architecture: x86_64kernel: 2.6.31-8-generic
Hi, I've made clone because I've checked that bugs is related to R600 Driver, and this is (as i think), better place for this bug Short Additional info from my side Since in Archlinux is new mesa/dri module for radeon this error starts occur. downgrade to older driver 7.5.1 result with inform that r600 library is needed and it runs software rendering. important info is that it's not connected with x86-64 but with all architectures. I will not put additional logs, because there are mostly the same like inside bug 23664. please look for them over there
Tomasz, you will need to use a newer kernel with drm support for r600. Please try a 2.6.32 kernel (currently at -rc6) and attach full logs if this does not help.
Upgrade to kernel 2.6.32_rc6 fixed the issue. Thanks for help.
