This bug is affecting me in Ubuntu 12.04, with kernel 3.2.0-32-generic, in a Dell notebook with 4 Gb of ram, ATI Mobility Radeon HD 3400 graphics. I'm using fglrx 2:8.960-0ubuntu1.1.
I have 5.8 GB of allocated space for /swap in a dedicated partition. I experience the same problem as described by Greg. If something has been written to swap (which I've monitored with htop), I can most certainly have intensive swapping issues when resuming after suspending. Not only kswapd0 gets 99.99% of disk usage (according to iotop), but often many other processes already running, like empathy, dropbox, etc, get high disk usages. Once swapping has stopped, the system sometimes has poor response and feels sluggish for a while, as there can be sporadic bursts of high disk activity following, for instance, a workspace switch, or invoking the dash. I'm attaching some logs (kern.log, dmesg.0, pm-powersave.log, pm-suspend.log, Xorg.0.log) in case they can be useful. ** Attachment added: "logs.tar" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/761432/+attachment/3425242/+files/logs.tar -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761432 Title: excessive swap (kswapd) usage on resume - caused by fglrx?
