Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 10.04 LTS:
linux-image-2.6.32-216-dove 2.6.32-216.33
Ubuntu 10.10:
linux-image-2.6.32-416-dove 2.6.32-416.33
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
