    In my case I think I only have the poweroff problem.
    I'm not aware of an open bug for this issue. It appears that many distributions are exhibiting the issue, so I don't know if opening an Ubuntu bug would be productive. The bug either resides in the Linux kernel or - more likely - is a hardware issue the kernel would have to work around.

    Currently testing out this fix. Note: If anyone wants to mess around with initi.d scripts, please make backups of them before modifying!

    Yep, sounds like the driver is enabling WOL. What does cat /proc/acpi/wakeup show?

    Can't you turn off Wake-On-LAN in the BIOS?

    Re: Possible Power Mangement Bug: HP DM1Z

    Interesting that some of those can wake up from S5 ( off ). Does one correspond to your ethernet port? What does sudo lspci show?

    It looks like this is a bios problem... it is indicating that the ethernet port can wake the system even when it is totally off, and probably also enabling wol, which means it doesn't shut off.

    I assume this is with the fix you have been testing? Can you disable the fix and check /proc/acpi/wakeup again to see if one of those changes to enabled?
