Comment 33 for bug 160413

For me WOL magically started working - I tried a couple of times during the last few days. The weird thing is that I am still running Intrepid on the machine, i.e.:
  Linux andromeda 2.6.27-11-generic #1 SMP Wed Apr 1 20:53:41 UTC 2009 x86_64 GNU/Linux

The only thing I changed kernel-wise during the last weeks (except for applying security updates if any) was that I migrated from KVM to VirtualBox, so kvm-intel is no longer loaded.

@Pierre-Yves: Are you by chance using kvm or is the module loaded on your machine (lsmod | grep kvm should do the trick)?
