[Debian] Re: Bug#606237: linux-kernel: poweroff-button fails on 2.6.32-5-openvz-686

[Ola Lundqvist]

Hi

I suspect that the problem is in the openvz patch for the kernel. My  
suspicion is that the poweroff button signal goes to vzeventd while it  
should not do that for VE0.

So the next step is to check the kernel code. I have forwarded your  
issue to upstream, but I have not seen any solution yet.

But this is only a suspicion.
