Alas, that kernel stops as before, with: OK load disk0s2:/boot/kernel.spare/kernel disk0s2:/boot/kernel.spare/kernel text=0x9877bc data=0x1905a8 data=0x0+0x79d260 syms=[0x8+0x10bc60+0x8+0x130430] OK boot Using DTB provided by EFI at 0x7ef6000.

Looks like the problem is something other than the kernel. The power supply pins are at 4.88 volts when boot hangs. That would be within spec for USB (5.0 plus or minus .25 volt) _except_ that the Pi3 is spec'd for 5.1 volts... That puts me within meter error of undervoltage. Thanks _very_ much for writing! bob prohaska
