So far, I have been able to reproduce this bug twice.
korganizer, the kde agenda tool is unable to close properly since I
upgraded to DragonFly-2.0. The process seems to stay in some kind of
zombie state.
When trying to reboot the system, the following messages are shown on the
console:
init: some processes would not die; ps axl advised

...

syncing disks... 1
done
umount of filesystem mounted from subaru4:/distfiles failed(70)
[diagnostic] cache_lock: blocked on 0xe16da678 "korganizerrcbvUSpw.new"
The machine then stays in this state forever; I have to use the reset switch.
Yeah, I got exactly the same with firefox3. I tried to kill it with 
"kill -9", but that wasn't possible. Then rebooting showed the same 
messages as above.
