So it looks like the regression was introduced in v3.3.
Can you test the following kernels and report back? We are looking for the earliest kernel version that has this bug:
v3.3-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc4-precise
If v3.3-rc4 exhibits the bug then test v3.3-rc6: v3.3-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc6-precise
If v3.3-rc4 does not exhibit the bug then test v3.3-rc2: v3.3-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc2-precise
