I was executing libhugetlbfs tests on a power6 box [9117-MMA]. One of the
sub test (shm-fork) caused the machine to crash. Here is the information :

Have attached the dmesg log extracted via xmon. The libhugetlbfs
tests [v2.0] are part of autotest framework [autotest.kernel.org].
The sub test that caused this was shm-fork. I have attached the
libhugetlbfs execution log.
Thanks
