The failing test is

         # Remote partition offline tests
         " C0-3:S+ C1-3:S+ C2-3     .    X2-3   X2-3 X2-3:P2:O2=0 .   0 
A1:0-1,A2:1,A3:3 A1:P0,A3:P2 2-3"

You can remove all the previous lines in the TEST_MATRIX to get to 
failed test case immediately eliminating unnecessary noise in your testing.
