** Description changed: Periodically I notice my system slows to a near stand still, and the hard drive light is constantly going. This seems to be a massive amount of disk i/o and it lasts for a long time (lets say 30 mins to put a number on it). I installed and ran iotop (`iotop -a`) and it seems to point to jbd2. From what I can see jbd2 is related to ext4 journaling, but I cannot figure out how to kill this operation. It might even be a red herring because I have also stopped the disk activity by kill either chromium or firefox. I need to understand what else I can do to troubleshoot this. $ lsb_release -rd Description: Ubuntu maverick (development branch) Release: 10.10 Up-to-date as of 16th June 2010. + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23. + AplayDevices: + **** List of PLAYBACK Hardware Devices **** + card 0: Intel [HDA Intel], device 0: ALC272X Analog [ALC272X Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + Architecture: i386 + ArecordDevices: + **** List of CAPTURE Hardware Devices **** + card 0: Intel [HDA Intel], device 0: ALC272X Analog [ALC272X Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: pgoodall 1372 F.... pulseaudio + CRDA: Error: [Errno 2] No such file or directory + Card0.Amixer.info: + Card hw:0 'Intel'/'HDA Intel at 0x56440000 irq 44' + Mixer name : 'Realtek ALC272X' + Components : 'HDA:10ec0272,1025022c,00100001' + Controls : 14 + Simple ctrls : 8 + DistroRelease: Ubuntu 10.10 + Frequency: Once a day. + HibernationDevice: RESUME=UUID=145f27a9-859a-4987-8132-ac878c832747 + InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Alpha i386 (20100602.2) + MachineType: Acer AO531h + Package: linux (not installed) + ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.35-6-generic root=UUID=11f96f8b-5e04-4e20-a201-0fa5d0fc07fa ro quiet splash + ProcEnviron: + PATH=(custom, user) + LANG=en_GB.utf8 + SHELL=/bin/bash + ProcVersionSignature: Ubuntu 2.6.35-6.9-generic 2.6.35-rc3 + Regression: Yes + RelatedPackageVersions: linux-firmware 1.37 + Reproducible: No + Tags: maverick ubuntu-une kconfig regression-potential needs-upstream-testing + Uname: Linux 2.6.35-6-generic i686 + UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare + dmi.bios.date: 12/22/2009 + dmi.bios.vendor: Acer + dmi.bios.version: v0.3304 + dmi.board.asset.tag: Base Board Asset Tag + dmi.board.vendor: Acer + dmi.board.version: Base Board Version + dmi.chassis.type: 1 + dmi.chassis.vendor: Chassis Manufacturer + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnAcer:bvrv0.3304:bd12/22/2009:svnAcer:pnAO531h:pvr1:rvnAcer:rn:rvrBaseBoardVersion:cvnChassisManufacturer:ct1:cvrChassisVersion: + dmi.product.name: AO531h + dmi.product.version: 1 + dmi.sys.vendor: Acer ** Attachment added: "AlsaDevices.txt" http://launchpadlibrarian.net/51504804/AlsaDevices.txt -- massive i/o renders the system unusable https://bugs.launchpad.net/bugs/595047 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
