Wysocki" , linux-acpi@vger.kernel.org, Linus Torvalds List-Id: linux-acpi@vger.kernel.org I found the same poweroff issue on my T61. It turned out to be related to the C state code disabling interrupts when it shouldn't iirc. Booting with 'idle=poll' seems to work around the problem. The "green screen" problem should be fixed (see the DRM git tree for details).
