Comment #14 refers to v3.2-rc7 not v3.3-rc7. See comment #7 for more details on the tested versions.
I just checked v3.3-rc7 and it is still broken, so it's not fixed.
It appears to be related to the config file, as opposed to the actual kernel code... see comments #10 & #17.
The result changed depending on which config file I used to compile the kernel. I was given a custom one for my L520 which works fine with the kernel git, while the Ubuntu default kernel config was causing the issue to happen.
My assumption is that there was a change of config defaults when v3.2-rc7, etc, were compiled, compared with the newer kernel builds (i.e. v3.3-rc7). It would be great to find out what this was, and have it reversed if possible?
It's also worth nothing that older kernel builds, such as the ones with 11.04 & 11.10 also had this issue. So it was resolved for a couple of kernel builds and then broken again.
Does that give you more to work with?
