Comment 19 for bug 287998

Hi Adam, you may be experiencing a different bug which in the Jaunty kernel. Some information is available here: https://bugs.edge.launchpad.net/linux/+bug/349314. That bug also contains a kernel which should fix the issue. Unfortuantely it seems that the patch was committed to jaunty, and then reverted. It will probably land as a stable-release-update, but you should be able to use it now and get performance back.
