Regression in kernel linux-2.6.20-rc1/2: Problems with poweroff

[Berthold Cogel <cogel@rrz.uni-koeln.de>]

Hello!

'shutdown -h now' doesn't work for my system (Acer Extensa 3002 WLMi)
with linux-2.6.20-rc kernels. The system reboots instead.
I've checked linux-2.6.19.1 with an almost identical .config file
(differences because of new or changed options). For pre 2.6.20 kernels
shutdown works for my computer.
