Yes, I just ran the test with 2.6.17.6. With CONFIG_DEBUG_SPINLOCK=y the test fails and the soft lockup situation often results. However, when built with CONFIG_DEBUG_SPINLOCK=n, the test passes, and runs rather quickly in comparison to when it fails.
I've attached a slightly updated version of the test case. It is a little more carefully crafted and prints some output so that you have some idea that it is working. [unhandled content-type:application/octet-stream]
