The first step is to figure out if this bug still exists upstream. In order to do that please install the current Natty kernel from https://launchpad.net/~kernel-ppa/+archive/pre- proposed?field.series_filter=natty . I suggest just copying the deb and installing directly ('cause its easier to remove afterwards):
wget https://launchpad.net/~kernel-ppa/+archive/pre-proposed/+files/linux-image-2.6.38-8-generic_2.6.38-8.40~pre201103300902_amd64.deb sudo dpkg -i linux-image-2.6.38-8-generic_2.6.38-8.40~pre201103300902_amd64.deb reboot, do your testing, then: sudo dpkg -r linux-image-2.6.38-8-server -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/719446 Title: systematic freezes on any kernel version post 2.6.35-22 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
