It is the default of debian and has been not changed. Content in /etc/default 
halt is:
..
HALT=poweroff
..

I have only added links for stop dbus after a lot of tries with kernel acpi 
and other kernel parameters on boot, doing always the same ritual:
- booting in a 'logged in kde'
- switching to text console
- execute 'shutdown -h now'.

Clearly I'm not absolutely shure whether the success depends on adding stop 
links for dbus, because boot and shutdown process is very complicate to 
understand. I think that adding a new script to the shutdown process should 
change the timing of the whole process, so maybe this has done an influence on 
shutdown process.

I agree to your opinion, maybe it is a hardware/bios/kernel problem on the 
notebook system which has not been detected in earlier situations (I use this 
notebook since lenny, run now about a year with squeeze and do the update to 
wheezy because kde in squeeze is very buggy). Sadly I'm not experienced enough 
in kernel debugging and have not the time for a deeper analysis.

I think you should please close the bug because it seems to be more a hardware 
problem or handle it as you like.

Thanks for your investigations.
Jürgen
