Hallo Knoppix Experts!

My HD installations of Knoppix 6.4.3 always ended after hours or days by
stopping boot sequence after hardware recognition and starting shutdown

F12 syslog dämon tells us:
Microknoppix Network Manager 2877 Warn blue error getting default adapter
The name org-bluez was not provided by any service files

Trying to start the supplicant

At this moment shutdown is initiated

Has anybody ideas how to find and eliminate the cause of this
disturbing bug?
Has anybody made similar experiences with HD installations of
Knoppix 6.x.x ?

Grateful for even a tiny hint, where troubleshooting might begin
or what else could be done
