ORA-600 kcratr1_lastbwr

I hit the error below during startup of my 10.2.0.4  installation running on Solaris 64 on

ORA-00600: internal error code, arguments: [kcratr1_lastbwr], [], [], [], [],[], [], []

Basically none of the instances start-up with srvctl command and log this error to alert log.

Tried to run manual startup of instances but no chance same error.

Quick search on MOS (yes it was working ) take me to the note 393984.1 (no bug number)

It says this is a bug on Enterprise Edition – Version: 10.2.0.1 to 11.1.0.6.0

Solution is manual recovery.
