This issue was fixed for me when I installed the 2.6.31-8 Kernel. You can install most necessary packages with apt-get:
sudo apt-get install linux-headers-2.6.31-8 sudo apt-get install linux-headers-2.6.31-8-generic sudo apt-get install linux-image-2.6.31-8-generic You can then install the linux-libc-dev package using wget: wget wget https://edge.launchpad.net/ubuntu/+source/linux/2.6.31-8.28/+build/1192025/+files /linux-libc-dev_2.6.31-8.28_i386.deb sudo dpkg -i *.deb Do a reboot (this is the last time you should have to hit the power button to reboot) and select the 2.6.31-8 kernel from the GRUB Boot menu. Once you have booted up, try a shutdown or restart and you should find that the problem has gone! I too am affected by the GRUB bug (bug 420077) mentioned above... let's hope they squash that one soon too! -- [Karmic] Hangs during shutdown with kernel 2.6.31-7 https://bugs.launchpad.net/bugs/418509 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
