Summary: lmbench test case fails on bf527 ezkit board

Details:

lmbench test case fails on bf527 ezkit board now, it didn't show the expected performance value when calling as :./lat_ctx -s 64 8, missing the numbers that should be on the second line.

get:

mbench3/bin/blackfin-Linux> ./lat_ctx -s 16 8^M

"size=16k ovr=51.85^M

8 164.58^M

root:/lmbench3

Case 4 ...PASS

/bin/blackfin-Linux> ./lat_ctx -s 64 8^M

"size=64k ovr=630.86^M

root:/lmbench3/bin/blackfin-Linux>

Case 5 ...FAIL

It looks ok on other boards and this bug was first seen at about Sep 24.
