Comment 2 for bug 1236041

Same symptom/problem here with 3.2.0-54. Switching back to previous installed kernel (3.2.0-51 in my case) solves the issue.

I suspect the regression comes from this commit:
https://lists.ubuntu.com/archives/kernel-team/2013-September/032287.html
  * xfs: fix _xfs_buf_find oops on blocks beyond the filesystem end
    - LP: #1151527
    - CVE-2013-1819

For what it's worth, the same change produced the same effects in redhat six months ago:
