While executing hackbench against today's next on a 4 way power6 box (9117 MMA), the machine crawled within few seconds with lots of OOM messages. I captured a Crash dump and was able to extract the dmesg log which i have attached here. This problem started with 0706 next release. 0703 worked fine. Kernel is compiled with SLQB and 64K page size. .config attached. Let me know what other information i can provide to find a solution for this problem.
