           CPU : AMD Athlon(tm) Processor(2-way); cpu MHz: 1194.857;    
                 cache size: 256KB
           Memory: total 513MB

Problem Description:
           Started a 96-hour hammerhead against apache server. The number of 
           sections to simulate(thread) was 50. After it ran for about 24 hours, 
           the system was crashed and got the following information on screen:

Code: 8b 50 0c 83 c0 0c 39 02 75 19 8b 01 83 f8 08 75 12 8b 41 6c

Steps to reproduce:
       1. Downloaded 2.6.0-test1 from kernel.org tree and built it, reboot
       2. Installed apache server(httpd-2.0.45) on system and start it
       3. Choose a client system with 2.4 kernel on it; 
          installed hammerhead-2.1.2; 
          cd to /etc/hammerhead; 
          vi post.scn file and put the following lines in it:
                NSample GET
                RGET /cgi-bin/test-cgi
                T0
          rm root.scn
          create a hammerhead scenario file to run hammerhead:
                Set up section number to be 50
                Set up run time to be 96 hours
          run the following command to start hammerhead:
                hammerhead -c hammerhead-scenario

      4. The system crashed after about 24 hours in my case.
