sysinstall / kernel crashes for at least 5 days

[Jan Stocker]

Hi...
i tried to install -current from snapshots.jp for more than 5 days but got
this reproducable error all the time.
If you try to delete a partition and create a new slice, than exit the
editor with 'q' it ends in kernel debugger, same if i use an existing slice
and try to enter the "distribution" section.

DDB output reads (this is copy/paste by pen & paper...):
