This will show exactly what I did. Hoping there's a simple fix for this. In theory, it should now be possible to enable IB support on a stock FreeBSD system in a few minutes, since we should be able to use loadable modules instead of doing a buildkernel, and IB support is now included in the base, making buildworld unnecessary: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211761 This is a big step toward enabling the use of stock FreeBSD systems in HPC. I had successfully used the IB stack before by loading the modules and doing a buildworld. Regards, JB -- Earth is a beta site.
