The bug is present in all the above three versions, v3.9-rc8, v3.9 and v3.9.1 from the mainline. I also tested with v3.8.13.2-raring from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.2-raring/ and the bug is NOT present there. Hope this helps.
Please feel free to ask any version you want tested. This is making a couple of our daily smoke tests failing, so helping you fix this would in fact help us.
