I just built 2.6.27.9-rc1 and disconnected the Windowz box several times.
For now smbd does not seem to go into a death spin any more, even though
as far as I can tell .9-rc1 does not contain Manfred'd latest patch. Not
sure what that means, if anything.

I'll keep running stable.9-rc1 and see what happens..

thanks all
Holger
