I do believe, that:
Package: linux-image-3.11-0.bpo.2-amd64
Source: linux
Version: 3.11.8-1~bpo70+1
Installed-Size: 125379
Architecture: amd64
Provides: linux-modules-3.11-0.bpo.2-amd64
Is also affected by this bug. The visible effect for me was that after 'apt-get dist-upgrade', which brought 3.11.8-1~bpo70+1 to my x86_64 system perfectly working on 3.10.11-1~bpo70+1 installation of nginx, which is configured to use 'epoll' as an event mechanism stopped working. At the moderate load nginx started to refuse socket connections or respond was coming after several minutes.
Switching to 'select' event mechanism, as well as rolling back to 3.10.11 fixed the problem.
