[The loader here has been modified to always do the usefdt=1 code. The modern VM_MAX_KERNEL_ADDRESS is in the kernel.] In trying to boot for other experiments I tried at the loader prompt: unload load /boot/kernel/kernel boot and: unload boot -v /boot/kernel/kernel Such combinations produced (typed from a picture of the screen, the missing text was really missing): GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb panic: Translation map has incorrect cell count (260/256) cpuid = 0 time = 1 KDB: stack backtrace: 0xc000000000f9e kdb_backtrace+0x60 0xc000000000f9e vpanic+0x258 0xc000000000f9e panic+0x3c 0xc000000000f9e moea64_late_bootstrap+0x2c0 0xc000000000f9e moea64_bootstrap_native+0x20c 0xc000000000f9e pmap_bootstrap_0xc8 0xc000000000f9e powerpc_init+0x440 0xc000000000f9efc0: at (And that is all.) === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
