Hi amit, What you mentioned is correct , dmesg or /var/log/messages display the crash log ,somehow I got this log even after the system crash. After obtaining the crash log we need to know the reason of crash. I want the document that guides me to find the reason of crash.
Thanks & Regards, Blprasad.
