(I also used WITH_DEBUG_FILES=3D, WITHOUT_CLANG=3D, and = WITH_DEBUG=3D in /etc/make.conf.) So buildworld, kernel was basically = just set up to have more of a debugging context around (including for = any ports builds). The result was new information about the PowerMac G5 boot hangups: The = screen is no longer blank when the G5 is hung up without there being a = Copyright notice yet. It says... > GDB: no debug ports present > KDB: debugger backends: DDB > KDB: current backend: DDB > [ thread pid -1 tid 1006665719 ] > Stopped at 0: illegal instruction 0 > db> (I had no ability to input at that point.) Normally the Copyright notice = would have displayed instead of "[...]" and what follows. (I do not = claim to have all the spacing, capitalization, and such correct above.) That text is constant from hang to hang when it hangs just before it = would normally output the Copyright notice: The numbers do not vary, = much less the other text. It has never failed until after the two KDB = messages are present. So far I've only tested one PowerMac G5, booting = over and over for a few hours. (I do not claim to be set up for remote kernel debugging. I just decided = to let GDB go along for the ride when I added DDB.) =3D=3D=3D Mark Millard markmi at dsl-only.net
