Urgent ORA-00600: internal error code

Following the replacement of a disk I did a mksysb restore on a AIX 5.2 machine running Oracle 9.2  

All the Oracle software, data files etc were on a tar tape that has also been restored.  

But now when I try to startup Oracle I get the message  

ORA-00600: internal error code, arguments: [3004], [1], [0], [0], [],
[], [],

[]

Does anyone have any advice or information on this error?
