3.3-RELEASE 'out of the box'
>Description:
A dump on a RAID5 vinum volume causes a freeze of the system. This 
happens at dump phase IV (dumping files). After this the system is not 
accessible by any key (No console switching, CTRL-ALT-DEL,...), only 
pressing RESET-Button or Power cycling helps.
>How-To-Repeat:
build a raid5 vinum volume, for instance my config:

(make diskslices with type vinum)
# disklabel -e da1e (type vinum)
# disklabel -e da2e (type vinum)
# disklabel -e da3e (type vinum)

(write a vinum config file)
drive d1 device /dev/da1e
drive d2 device /dev/da2e
drive d3 device /dev/da3e
volume raid
  plex org raid5 256k
    sd length 512m drive d1
    sd length 512m drive d2
    sd length 512m drive d3

(set it up)
# vinum
->create vinum.cfg
->init -vw raid.p0 (this needs some time!)
->quit
# newfs -v /dev/vinum/rraid
# mkdir /mnt/raid
# mount /dev/vinum/raid /mnt/raid

(populate it)
# cp -R /usr/share/doc/usd /mnt/raid

# cd /
# dump -0au -f /dev/nrsa0 

Now you hear some hd activity, dump runs through its phases and when
phase IV is reached, the system freezes.
