uname command output

Hi,

I am using ubuntu in my system for last one month. when i run the uname command with options i and p, it is showing unknown output. It means Ubuntu was not installed properly in my system or problem with the system hardware? I am pasting the out below. Can anyone please help me.

root@room1-desktop:/home/room1# uname -a
Linux room1-desktop 2.6.24-19-generic #1 SMP Wed Jun 18 14:43:41 UTC 2008 i686 GNU/Linux
root@room1-desktop:/home/room1# uname -i
unknown
root@room1-desktop:/home/room1# uname -p
unknown
root@room1-desktop:/home/room1#


Thanks in advance.
