URGENT: Panic Problems

Hi, I am having a nightmare at the moment. I woke up this morning and my system had panicked. It is a MacPro with a software RAID 01 configuration. I rebooted and the system tried to start, got some way into the init it appeared even though I did not having it booting verbosely and then panicked again. The next time it would simply not recognize any bootable drive. It seems that I can get into single user mode, but cannot load the root fs.

I drove a couple hours away to an Apple store and we spoke for a while, but they refused to do anything as they were not allowed to do so. One fellow there seemed fairly confident that it would rebuild properly as we had, at that time assumed that a drive was bad. They listened and one of the drives appeared to sound clunky as though it had the click of death, so I figured that to be true.

I brought the machine home with a couple new drives to replace the bad one with, took each drive out and listened to them initialize outside of the machine as the store was quite noisy and unfortunately that was the standard initialization of each machine. It appeared as though there was nothing really physically wrong with the drives, plus when printing out the raid information from diskutil none showed to be degraded nor did they have any SMART failure.

I had already, though, tried to replace the drive and it had restarted to build, but about 10 minutes in the OS panicked again. So then that was when I thought that perhaps the drive was not bad and then replaced the new drive with the old one to see what would happen. Same thing, it tried to rebuild the array and then about 10 minutes in, it would panic. This panic happened on a Tech Tool Pro boot eDrive and an install DVD. It also appears to happen when a rebuild is not running and the OS is simply idling.

I did not have enough time to write the entire panic stack down here, but could reproduce it and go back and type it up for you in this email. The first line in the backtrace was had to do with: com.apple.comkext.aty_lamna

The last line I believe had something to do with the Nvidia graphics card if I recall correctly.

I am in desperate need to recover this array. I will loose 2 weeks of work plus all of my family photos and some videos if I cannot rebuild this. I fear that there is more of a root cause here vs. RAID failure. Any thoughts or ideas as to how I should track this down and recover from this issue?


Desperately yours,

-George
