-------------------------------------
TestCase ./thugetlb_overcommit 1
FAIL: migration failed.
Unpoisoning.

 Num of Executed Test Case: 1 Num of Failed Case: 1

Testcase failure is expected because hugepage migration is not enabled in the Ubuntu configs. Please not that we no longer see softlockups. The patch fixed that bug.
