Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I am currently affected by this bug. I would like to help, but it's not at all obvious to me what tools I would use to investigate this. I am an experienced software developer, just not in the kernel, nor in the kernel's debugging tools/process. I am subscribed to emails for this bug, and would gladly do anything helpful to solve this as it impacts my development.

Thanks,

Derrell
