Hi Vladislav, thank you for sharing your experience with this issue. I'll give your hint a try. Are there any negative impacts diabling apicd? (I have to admit I never thought about its role)
A call is open. I'm very curious what we hear about that.

Of course what you see is a bug in a BMC, it should do hard off on a 'chassis power off' command. For graceful shutdown (with proper ACPI signalling) there is a 'chassis power soft' command. I'd report that to vendor (although that may be implemented that way wittingly). > > I'll offer more informations when I get feedback to this > behaviour. > > Best regards > Andreas > > > -----Ursprüngliche Nachricht----- > Von: linux-ha-boun...@lists.linux-ha.org > [mailto:linux-ha-boun...@lists.linux-ha.org] Im Auftrag von Marek Grac > Gesendet: Montag, 15.
