Clues? Console, Runlevel 3 login, immediate boot-out

Can anyone offer any clues? Under SuSE 9.3, in either runlevel 3 or switching to console from KDE (<Ctrl><Alt><Fx>), I can login and the system shows me I have mail and when my last login was. But it immediately then logs me out, with no other messages and no new messages are added to /var/log/messages about this. It happens whether I login as root or a normal user. Everything else seems to be working fine, including x-term and konsole sessions under KDE. -- AD Marshall Web:  http://h0lug.sourceforge.net Zone: ICT (IndoChina Time; GMT/UTC+7) GPG/PGP Key Server: hkp://subkeys.pgp.net
