I tried installing 10.1-BETA2 directly from the 10.1-BETA2 MANIFEST and = *.txz files (via bsdinstall) to an SSD. The result booted the GeForce4 = Ti 4600 PowerMac G4 just fine. It appears that the additions of "options DDB" and "options GDB" to = GENERIC (and then doing buildworld kernel ...) may be what lead to the = boot time hang for the GeForce4 Ti 4600 video board based PowerMac G4. = The alternate is that WITH_DEBUG_FILES=3D, WITHOUT_CLANG=3D, WITH_DEBUG=3D= contributes or verbose_loading=3D"YES" in /boot/loader.conf does. Or = just building from source from a powerpc/GENERIC context (on a G5 = PowerMac) leads to the issue. At this point I've no clue why the GeForce4 Ti 4600 combined with any of = those alternatives leads to the hang. I may never know since the hang is = silent and rather early in the boot sequence. The radeon based PowerMac = G4's did not hang. Nor did the GeForce 7800 GT PowerMac G5's. =3D=3D=3D Mark Millard markmi at dsl-only.net On Sep 17, 2014, at 11:01 PM, Mark Millard <markmi at dsl-only.net> = wrote: For FreeBSD 10.1-BETA1 the 1.4GHz Dual-processor PowerMac G4 (yep: 4) = with a NVIDIA GeForce4 Ti 4600 in it always hangs after: > GDB: no debug ports present > KDB: debugger backends: DDB > KDB: current backend: DDB without writing out the Copyright notice or anything else.
