Darwin Kernel Version 8.0.0...panic: We are hanging here...

Hi just purchased a quad 2.5 G5 from my work. It had Tiger already installed, but I wanted to partition the internal hard drive. I put in the Tiger install disc and went through the process of partitioning and restarted. Now I am getting the a black screen with a bunch of writing on it and it ends with "panic: we are hanging here...". I've never come across this before in partitioning the HD, but I must have done something wrong. Any help is much appreciated!

Thanks.

G5, Mac OS X (10.4)

Hi-

You have a kernel panic.

After you partitioned, did you reinstall Tiger?
Or, did you just try to partition?

Can you boot to the OS X install disc?

Hello,

I cannot boot to the install disc, which is still stuck in the tray. I've tried removing some RAM, but that doesn't seem to help. As soon as I boot up I get a black screen with the kernel panic. Any help will be much appreciated!!

Pull the hard drive out, and boot holding C.
Anything?

The Tiger disc is a retail disc (Black with a Silver X)?
Or, is it from the original OS install discs (gray)?

Put the hard drive back in.
Try a Safe Mode boot (hold Shift while starting).

Try a boot to Single User (Command+S) while starting.
In Single User, use the instructions listed for fsck on this page:

What are the results from either of these?

The Tiger disc is a retail disc.

I'll try these two things and let you know shortly.

Thanks again for the help, I really do appreciate.

Okay

I tried holding down shift at start up, but I still got the panic, though there wasn't as much text on the screen this time.

Command+S gave me the kernel panic again as well.

Any other ideas?

Is the Tiger disc 10.4.2 or later? If so, fine. If earlier, that is the problem.

Currently, all connected hardware should be the keyboard, mouse and monitor only. The keyboard and mouse should be Apple.

Do you have the original install discs? They should accompany the machine, as they are of no use to any other machine other than the Quad.

If you have the original install disc set, there is one with the Apple Hardware Test on it.
You need to boot to that and run the AHT.

If you can't get the Tiger disc out of the optical drive, pry the slot cover open on the tower, and locate a small hole in the front of the optical drive. Insert a straightened paper clip to eject the tray manually.

Insert the AHT disc, hold C while starting, and run the full set of hardware tests.

If possible, I need you to read the text in the panic report, and look for the type of panic; "data access" "unaligned frame", "frame not mapped", etc., and look for the word "Backtrace", and note the lines immediately after "Backtrace".

Okay, it looks like it's a data access panic. It says:
"panic(cpu 0 caller 0xFFFF0003): 0x300 - Data access".

I've also located the word "backtrace" a number of times. The first one says:
"Latest stack backtrace for cpu 0: Backtrace: 0x00095565 0x00095A7C 0x00026838 0x000A8184 0x000AB880".

I do not have the original install discs as my work did not have them. I do have an older G5 and I have the 10.3.2 install discs for those. Could I use those and then upgrade to Tiger? I'm pretty positive my install disc for Tiger is for 10.0.

And I currently have only a mouse, keyboard, and monitor connected.

Hi-

Using an OS version earlier than that which is compatible in your machine is why you have this problem.

You need Tiger 10.4.2 or later.
Earlier versions, and discs from other machines will not work.

Get a retail Tiger 10.4.3 (or later) or get Leopard 10.5.6 (current retail version), or get the original discs from work.

So if I get the current Leopard version, this disc will have the AHT on it and this should solve my issues? Thanks again for all the help, I appreciate it!

Only the original discs have the AHT.
If you can't get the original disc set, then contact Apple Support to see if they can provide replacement.

Your problem should be solved simply by inserting an OS X install disc of the proper version into the optical drive.
The hard drive, in the partitioning process, has lost the previous installation.

You will need to get the appropriate retail disc (anything later than 10.4.2). Boot to the OS disc, and in the window after language selection, use Disk Utility to partition and format the drive. Then, install the OS.
