DB shutdown abort after startup nomount

I tried to apply a patch to resolve RAC shutdown problem.

After the patch was applied to the nodes, all the nodes failed to startup again.

No core dump no error found in the alert log.  Startup nomount seems to be normal but return "ORA-03135: connection lost contact" when put it "show parameter ...".  The audit file record a shutdown issued by the same sqlplus.

Last few lines of the alert log:
