Bug Description
__d_move crashes in second d_ancestor check where it finds that one of parents for "dentry" variable is NULL.
Call comes from sysfs_lookup-
I have take picture from oops report but I don't have cable for the camera. But I will upload the picture later when I get my hands on the cable. Too bad console font was a bit too large to capture the begin of the oops report.

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag(Only that one tag, please leave the others). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text.
If this bug is fixed by the mainline kernel, please add the following tag 'kernel- fixed-upstream- KERNEL- VERSION' . For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel- fixed-upstream- v3.2-rc1' .
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' . If you believe this bug does not require upstream testing, please add the tag: 'kernel- upstream- testing- not-needed' .
Thanks in advance.
