I have a 2007 Mac Pro (OS X Tiger 10.4.11) that cannot boot up anymore since a few days. I see the grey screen with the apple logo and the rotating circle. After a minute or so I get a kernel panic. All peripherals except the Apple keyboard are disconnected.
I tried booting from my install DVD, this gave a kernel panic too.
When booting multiple times in safe mode, this is the last line on the screen: "localhost mDNSResponder: Adding browse domain local"
What I already tried:
-Downloaded and burned another Install DVD, same problem (first disc is original)
-Switched the memory modules and booted with just 1 inserted
-Ran the Apple Hardware Test, no problems found.
-Replaced the DVD drive
-Ran fsck -fy , no errors
-Cleared the PRAM
