Comment 33 for bug 96480

The number of users affected by this bug appear to be few, but its annoying nonetheless. Kernel releases subsequent to 2.6.20-12 fix a host of other problems which do affect a great many people, which is why we cannot release 2.6.20-12. I also asked how to get the 2.6.20-12 kernel:

"if they can manage to install, then they can download it from the "builds of" thing at the top left of https://launchpad.net/ubuntu/+source/linux-source-2.6.20/2.6.20-12.20 - e.g. https://launchpad.net/+builds/+build/312897 -> Resulting binaries -> https://launchpad.net/+builds/+build/312897/linux-image-2.6.20-12-generic -> http://librarian.launchpad.net/6895136/linux-image-2.6.20-12-generic_2.6.20-12.20_i386.deb"

In summary, do this:

wget http://librarian.launchpad.net/6895136/linux-image-2.6.20-12-generic_2.6.20-12.20_i386.deb
sudo dpkg -i linux-image-2.6.20-12-generic_2.6.20-12.20_i386.deb
