My experiments with controlling the mftb value relationships from cross-core (/cross-socket) contexts avoided the fan behavior and the shutdown/reboot timeouts in my testing. But I've no evidence associated with network interfaces being tied to that. In fact, I've never had ethernet interface problems, other than usefdt=3D1 swapping which was 0 vs. which was 1. (The fdt conversion reverses each sibling list but the code using the nodes is based on fixed traversals, independent of lack vs. presence of a usefdt definition or the value it is defined to.) I've basically only used ethernet, so I can not comment on other networking interfaces. (I also run with patched code so that the fdt conversion preserves the order of sibling lists, leaving the fixed traversals alone. I also have some OF_xref_from_node and OF_node_from_xref (lack of) usage corrections involved. I'll avoid listing more here. But I do not get distinct traversal results from usefdt mode.) > This is the first time I try to do a buildworld after moving to clang > (which was done by a reinstall).

(I've switched to ELFv2 for powerpc64, but, prior to that, my context was based on experimental system-clang ELFv1, either built by system-clang or, at the time, devel/powerpc64-gcc .) =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
