10gR2 RAC Database instance & CRS shutdown Hanging

Folks

Instance & CRS shutdown both seem to be Hanging for an internal Test 10gR2 RAC Setup.

What approach / action should be considered? Will O.S. RE-BOOT of Both the Nodes in the Current State resolve the issues?

P.S.

Oracle version - 10.2.0.2

Solaris 10

On Node 1

Unable to shutdown the instance using srvctl & "shutdown immediate". Both Hanging.

Following message is being repeatedly Written infinite Number of Times to the "alert_PNBRAC1.log"
