This appears to be a fundamental problem to me, because max_nr_of_sg=0.
In ofed-1.2-alpha we removed do_mmap() from kernel space, which
also affects user space in that both kernel and user space components
have to be from the same code stream.
Have you remove previous execs and libs from ofed-1.1.1 using
ofed's uninstall.sh (located in /usr/local/ofed)?
Did you download the daily build package from
http://www.openfabrics.org/builds/ofed-1.2/ or from Vladimir's git?
Did you build ofed-1.2 using the delivered install.sh script?
I tested OFED-1.2-20070301-0600.tgz this morning on sles10
and did not encounter this problem.
