I have an IBM x346 server, 2 cpu XEON 3 GHz EM64T , 2 Gb RAM, RAID 7k Installation of SL 4.2 i386 works. Installation of SL 4.2 x86_64 hangs always when rebooting, even in the first reboot during installation sequence. The last message on the console after the command "reboot" is: ... "Restarting System" and nothing happens after this message. No relevant error messages are found in /var/log/messages. The "shutdown" command works correctly. Also with SL 4.1 x86_64 the result is the same, no rebooting. Any suggestion? Giovanni -- Giovanni Bracco ENEA INFO (Servizio Informatica e Reti) Via E.
