[The same SSDs boot the 2 PowerMac11,2 G5 (2-socket/2-core-per-socket) just fine. I temporarily have access to the PowerMac7,2 and a different 11,2 G5 that has only 12 GiBytes of RAM --but not the 16 GiByte one. ] Both powerpc64 FreeBSD (built via system-clang) and 32-bit powerpc FreeBSD (built via gcc 4.2.1) fail the same way. The failure looks like (from a picture of a powerpc64 attempt): Booting [/boot/kernel/kernel]. . . Error -2 adding node /cpus/PowerPC,970 (PowerPC,970), skipping Kernel entry at 0x100100 . . . (and that is the end of the output). Note: I had modified the kernel to not require an explicit usefdt=1 --in fact giving not control in the other direction either. So, always using usefdt=1 mode. I had intended to stick with testing usefdt=1 mode. Result: As stands I do not have media set up that can boot the 7,2 . This means that I've not checked any contrasting cases that do not involve usefdt=1 style behavior. Thus my attribution of the problem to usefdt=1 style behavior is not validated. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
