Comment 4 for bug 1447664


>Did this issue start happening after an update/upgrade?

No, I also had this issue. I tested with multiple OSes and kernel versions. I tested the issue with kernel 2.6.39,
and three Ubuntu live CDs 12.04, 14.04, and 15.04 (which was released today). I, however, will consider testing with kernel 4.x.
