I've been using -ap with ofwdump but it might not be essential to the observed problem.] In trying to track down a problem, where I wanted to use ofwdump -ap information, I ended up finding and checking old boot media that happen to be around that target powerpc64. The oldest failing: -r333594 (an 12.x-CURRENT time frame) The newest working: -r302214 (an 11.x-CURRENT time frame) (No versions around between those.) (As almost always, my powerpc64 builds are experiments targeted via toolchains more modern than gcc 4.2.1 and the like.) Those listed above long predate any useful usefdt boots/operations in my context. The 2 powerpc64 builds before -r302214 worked. (The original problem that started this is that usefdt skips some ofw nodes. Then I found that not having usefdt mode lead to crashes for ofwdump -ap . So I went looking at the few historical builds that I found.) Modern powerpc64/head FreeBSD without use of usefdt mode fails somewhat differently: scrolling console messages going by too fast for me to read after starting ofwdump -ap. (It might be back-traces.) No ability to get to the ddb> prompt and no access via the network. But modern FreeBSD has various blocking issues before one can even get this far. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
