Comment 2 for bug 1033568

Hi Kate,

We know that the latest Precise kernel, which is based off of 3.2.14, has the bug. We next need to identify the first Quantal kernel that fixed the bug.

Can you test the following kernels and report back the first one that fixes the bug:

v3.3 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-precise/
v3.4 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/
v3.5-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc4-quantal/

The v3.3 kernel will only require one .deb file to be installed: linux-image-3.3.0-030300-generic_3.3.0-030300.201203182135_amd64.deb

However, the 3.4 and newer version require both the linux-image and linux-image-extra .deb packages to be installed.

You can install the .deb packages from the command line like the following(v3.4 example):
sudo dpkg -i linux-image-3.4.0-030400-generic_3.4.0-030400.201205221131_amd64.deb
sudo dpkg -i linux-image-extra-3.4.0-030400-generic_3.4.0-030400.201205221131_amd64.deb

A reboot is then required to boot the new kernel. You can access the GRUB menu while booting by holding the shift key. That will allow you boot back into the original kernel.
