** Description changed: Binary package hint: linux-source My TV card (Leadtek Winfast TV2000/XP) seems to work only with acpi=off passed to kernel. When ACPI is enabled, the picture is just a slideshow, trying acpi=noirq makes the slideshow just a little faster. This can be reproduced with any kernel from 2.6.29 to 2.6.32 from mainline ppa, I tried both Hardy LTS and Karmic, didn't try older kernels as they fail to boot. This is no X problem, the behavior can be reproduced even without X and with nvidia module unloaded just by capturing a bit of video. I tried also to recompile bttv driver with IRQF_SHARED or IRQF_DISABLED explicitly declared, it didn't change a thing. The rest of PCI hardware seems to work fine. When the picture is stuttering dmesg reports: [ 78.044297] bttv0: timeout: drop=301 irq=1092/1092, risc=595e2b3c, bits: HSYNC OFLOW [ 78.604537] bttv0: timeout: drop=312 irq=1132/1132, risc=56822b5c, bits: HSYNC OFLOW [ 1081.948327] bttv0: timeout: drop=323 irq=1192/1192, risc=69dad6bc, bits: HSYNC OFLOW Edit: The card works normally after disabling C1E in BIOS. It seems to be a duplicate of this bug: http://bugzilla.kernel.org/show_bug.cgi?id=13911 If BIOS does not allow to disable C1E the idle=mwait kernel parameter may be used to prevent CPU from entering C1E. + + + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24. + ApportVersion: 1.23-0ubuntu3 + Architecture: i386 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: ubuntu 3389 F.... pulseaudio + CRDA: Error: [Errno 2] No such file or directory + Card0.Amixer.info: + Card hw:0 'CA0106'/'Audigy SE [SB0570] at 0xdc00 irq 19' + Mixer name : 'CA0106' + Components : '' + Controls : 35 + Simple ctrls : 18 + CasperVersion: 1.287 + DistroRelease: Ubuntu 11.10 + IwConfig: + lo no wireless extensions. + + eth0 no wireless extensions. + LiveMediaBuild: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) + MachineType: System manufacturer System Product Name + Package: linux (not installed) + ProcEnviron: + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcKernelCmdLine: file=/cdrom/preseed/hostname.seed boot=casper initrd=/casper/initrd.lz quiet splash -- + ProcVersionSignature: Ubuntu 3.0.0-12.20-generic 3.0.4 + RelatedPackageVersions: + linux-restricted-modules-3.0.0-12-generic N/A + linux-backports-modules-3.0.0-12-generic N/A + linux-firmware 1.60 + RfKill: + + Tags: oneiric running-unity + Uname: Linux 3.0.0-12-generic i686 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare + dmi.bios.date: 09/10/2010 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: 0901 + dmi.board.asset.tag: To Be Filled By O.E.M. + dmi.board.name: M3N78-EM + dmi.board.vendor: ASUSTeK Computer INC. + dmi.board.version: Rev X.0x + dmi.chassis.asset.tag: Asset-1234567890 + dmi.chassis.type: 3 + dmi.chassis.vendor: Chassis Manufacture + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr0901:bd09/10/2010:svnSystemmanufacturer:pnSystemProductName:pvrSystemVersion:rvnASUSTeKComputerINC.:rnM3N78-EM:rvrRevX.0x:cvnChassisManufacture:ct3:cvrChassisVersion: + dmi.product.name: System Product Name + dmi.product.version: System Version + dmi.sys.vendor: System manufacturer ** Attachment added: "AcpiTables.txt" https://bugs.launchpad.net/bugs/509219/+attachment/2585060/+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/509219 Title: bttv driver latency issues with AMD C1E enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/509219/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
