Mon Feb 19 15:14:00 GMT 2007 

My environment is kernel-2.6.20-rc6,elfutils-0.124,systemtap--20070217.

When I executed the tests on ppc64 system,I got the below error in dmesg. But
system didn't crashed and tests are still running.

But these messages are getting generated frequently,making the  system less
responsive.
