I may have a similar pb.
I have Mandriva 2006 which worked well till I tried to install the *torrent* packages.
After the installation the torrent logo screen would come up briefly then disappear.
I rebooted the PC and then the system got stuck trying to start mandi daemon.
then timed out and gave me localhost login:
I tried "chkconfig mandi off" (apparently it is not essential to the system)
which allowed the startup to go further but still stopped with the localhost login:
as a newbee I don't know where to go from here can anyone help?
