Problem with booting using nosmp

view story

http://unix.stackexchange.com – I tried to install RHEL 5.1 in an i3 processor machine with 2gb ram. So after installation I tried to boot up, but unfortunately the machine got freezed showing Starting udev. I dont know exactly what the reason is. For finding that I rebooted with disabling the quite mode. I was not able to find any problems. I made a lot of googling and found a solution from a forum. Booting using nosmp. This worked well, but I just want to know that whether is it a good practise, and also will it make any problems. I will be running Oracle 11g in that particular machine. The machine will be a middleware (HowTos)
