This issue does still affect the latest upstream 3.13 kernel.

It affects:
kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11.6-trusty/

It also affects:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15.7-utopic/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15.10-utopic/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.1-utopic/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc1-utopic/

It does not affect:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc2-trusty/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15.6-utopic/

I've also tested most versions between v3.15-rc2-trusty and
v3.15.6-utopic, none of which are affected. The regression returned in
v3.15.7-utopic which is affected.

Note: In bug #1300349 I mistakenly wrote that v3.15.6-utopic is
affected, but it is not. Version v3.15.7-utopic is affected.
