I'm in the process of repurposing my G5, and decided to reinstall Leopard. When I tried to boot off my retail Leopard DVD, the G5 would get to the "spinning wheel" (is there an official name for that?) on the white screen and then suddenly reboot. This happened every time I tried to boot off of it. When I rebooted off the hard drive, I saw an error message in the log that the PMU had forced a shutdown with a reason code of -122. Preliminary research indicated a power supply problem, but I wasn't buying it since it only happened when booting off of the DVD and the G5 was rock-stable booted off the hard drive. Sure enough a PMU reset cured the problem. However, I'm wondering if it's possible I have a real problem. Does anyone know anything that might cause the Leopard DVD to trip what seems to be a purely hardware error? Faulty DVD or Superdrive crossed my mind...
More problems...reinstalled Leopard 10.5.1 and used Migration Assistant to recover from backup. However, when I rebooted from hard drive the G5 would shut down again when booted from hard drive this time. However, I was able to boot from the DVD and reset the password (the migration didn't pull that over properly.) Once I removed the Leopard DVD from the drive, the system booted normally. Everything appears OK, but I did notice this odd message in the log:
IOPlatformControl::registerDriver Control Driver AppleSlewClock did not supply target-value, using default rtclock timebase_callback: late old 1000000000 / 33332415 new 1000000000 / 33332357
Is it trying to tell me my hardware clock is out of whack, or just wacky?
