After getting it to build correctly, installing it, and configuring it,
I am getting a crash in rdma_ucm. That and for some reason, there is a
dependency upon ipv6.ko which depmod doesn't pick up. The latter is
solvable easily, but the former is troubling. Here is the snippet from
the messages file

I bring ipoib for testing (pinging) hosts, as well as having some of the
ssh traffic cross it. Sometimes quite useful.
Is the above a known problem? Should I file a bug report? The tainted
kernel is likely due to the arcmsr driver, though it is open source, so
I am not sure what is "tainted" about it.
