Oh yeah, this... i can clearly remember back then when on a then mid- range machine with a lot of compiling (gentoo => 100% cpu �[U+1F923]�) and filesystem work, VLC used to play an HD video stream even under heavy load without any hiccups and micro-stuttering.. It was impressive at the time.. and then.. it broke �[U+1F928]� -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/595047 Title: Frequent swapping causes system to hang Status in Linux: Fix Released Status in linux package in Ubuntu: Incomplete Bug description: 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.
