some of WHCK test cases are failing

Hi
I am running WHCK test on my serial driver but “Fuzz Misc API test” test case is failing while running “run test”.
I tried to analyze the root cause of failure but i didn’t find any proper log file to analyze.
so please any body tell me how to analyze the cause of this failure.

Hi:

This issue was just recently discussed on Aug. 19, 2014, seems to be a
reasonable starting place for your Fuzz issue as well.
