Unable to shutdown or restart after update from 10.5 to 10.6

Question

Hi,
I'm getting nuts with this.
After upgrading from 10.5 to 10.6 I'm unable to restart or shutdown.
The system hangs on a blue screen with a spinning wheel. I did an
update, not a clean install (that would be a horror trip with a re-
install AND reconfiguration of 50+ apps and is not really a solution :-().
I've read, that this problem occurs not very often but I'm not the
only one, who has it. Via internet searches I tried a lot but - nope.
I'm trying to find out, what causes the problem but nothing helped
me out of this trap.
I tried the following:
- PRAM reset
- System Management Controller (SMC) reset
- disabled all StartUp Items
- relocated the following folders to another location:
/Library/Preferences
/Users/myaccount/Library/Preferences
- did all maintenance procedures with Cocktail (Snow Leopard Edition)
- cleared all caches
- ran scripts: daily, weekly, monthly etc.
- took off all peripherals (USB, FireWire)
- removed third party Extensions out of /System/Library/Extensions
No success.
When the system hangs, the console looks like this:

I uninstalled Parallels Desktop too, but that did not the trick. Something
else must cause this problem. I'm driving crazy %-/
Anyone, who can help me out here? It's incredible and extremely annoying.
thanks a lot in advance and regards,
Josch

Hi Barney,
thanks a lot for your answer.
No - the above console log was with Parallels installed. But that
makes no difference. I did an uninstall and the problem still occurs.
Now (after uninstall of Parallels) the console log looks like this:

and after the last line it seems to hang.
A very strange thing. Hope someone can help.
Kind regards,
