I cloned the gits tree ok.
I'm testing now, but crashing in ibv_open_device because it branched to
0 due to the NULL amso lib alloc_context. This all worked before, so
something changed maybe. I recompiled everything but that didn't help.
Dunno what's up exactly. I'll probably not continue debug on this until
the middle of next week due to priorities. But I'll email back once I
learn more...
Thanks,
Steve.
