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. The same SSD boots an ATI Radeon 9000/PRO If (AGP/PCI) PowerMac G4 of = the same PowerMac model just fine. (I give uname -a and build details = later.) The same SSD also boots a PowerMac G5 with a GeForce 7800 GT = video board just fine. Other than the SSD, video board, and memory, = there is only basic stock equipment in the PowerMacs. The two G4's match = for those details as well: only the video boards are different models = and the amounts of RAM match. And my older 10.1-PRERELEASE #0 r271215 boot SSD still boots the GeForce = Ti 4600 PowerMac G4 just fine. While the place for the boot-hang is suggestive, I've nothing beyond = that indicating any relationship to the random PowerMac G5 boot problem = at the same place in the display sequence. And on the G4 DDB is not reporting anything, unlike on the G5 when it = hangs there. Context for failed boots off the GeForce Ti 4600 PowerMac G4 (I've not = tried much variation from this so no claims of essential status for any = of it): > FreeBSD FBSDG4S1 10.1-BETA1 FreeBSD 10.1-BETA1 #1 r271610M: Wed Sep 17 = 21:47:20 PDT 2014 root@FBSDG4S1:/usr/obj/usr/src/sys/GENERIC = powerpc The "M" status of r271610M (now that I "make -j 8 buildworld kernel" = based on svn materials in /usr/src/) is from the GENERIC modification in = the modifications listed below. The non-default things are... A) Adding to /usr/src/sys/powerpc/conf/GENERIC: "options DDB" and = "options GDB". B) Having /etc/make.conf use WITH_DEBUG_FILES=3D, WITHOUT_CLANG=3D, = WITH_DEBUG=3D, as well as having a WRKDIRPREFIX=3D(path not listed = here). C) Having /boot/loader.conf with just: verbose_loading=3D"YES". Context for working boots of the same GeForce Ti 4600 PowerMac G4: > FreeBSD FBSDG4S0 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #0 r271215: = Sat Sep 6 23:56:15 PDT 2014 = root@FBSDG4S0:/usr/obj/usr/src/sys/GENERIC powerpc /usr/src/sys/powerpc/conf/GENERIC was not modified at all.

But /etc/make.conf uses WITH_DEBUG_FILES=3D, WITHOUT_CLANG=3D, = WITH_DEBUG=3D, as well as having a WRKDIRPREFIX=3D(path not listed = here). /boot/loader.conf empty. =3D=3D=3D Mark Millard markmi at dsl-only.net
