[Bug 962189] [NEW] dkms module is not automatically rebuild when installing new linux-image package

[Ralf Heiringhoff]

Public bug reported:

Hello all,

I've noticed that the openvswitch_mod and brcompat_mod modules are not
automatically rebuild when I've upgraded to the latest linux-
image-3.2.0-20-generic, thus rendering my openvswitch config unusable
after a reboot to said new kernel.

Manual rebuilding and installation worked as expected:
