I tried to execute this test on the following driver: openib_gen2-20060420-0800, svn REV=6520 (trunk) and i get the same results.

Here are the results of this test execution with all of dapl provider names:
OpenIB-cma			: passed
OpenIB-cma-ip		: passed
OpenIB-cma-netdev	: passed
OpenIB-scm1		: never ends

i guess that as you suspected, the problem is with the scm provider.
