Deciphering a Kernel Panic Log

[jessiegirl]

Hello!
i just installed a g5 powermac running osx server 10.4.2. just for a little background on the box, it has an additional hard drive installed, and the two drives together are configured as a mirror. the only other software running on it is retrospect.

out of the box it was happy for the first week. but since the first day of on-site install, it has been getting kernel panics. the first couple were the first day of the on-site install, while i was restoring data on it from an 800 gb firewire drive. but once i removed the drive, it seemed to be fine. at ran two full days with no problem, until yesterday! it kernel panicked again. so now i'm at a loss for ideas. so... here is my panic log. just wondering if any body can tell what might be causing this (or the first place to look!)

thanks in advance!

Hi,
I would love to figure out what is com.apple.iokit.IOATAFamily.

My G4 recently started to kernel panic with this backtrace.
Cheers

 

[mike12]

sounds to me like it is the input/output for ata devices. have you scanned the drives for smart errors ? are you using a pci controller?

 

[step_andy]

Yes, I have SIIG SATA PCI card installed with 2 Maxtor 250 Gig SATA drives connected to it. One of the Maxtors is a boot drive, 2nd is for data.
I also have ATA drive connected to original ATA bus.

These crashes started after I adjusted disk sleep preferences in Energy panel.

I reverted the changes, but kernel crash still presists and it would crash after about 3 or 4 minutes every time I wake my G4 from deep sleep.

Speaking of PCI cards, Apple profiler reports this SATA card as ATA and both SATA drives as PATA. I e-mailed ti SIIG and they havent figured out as yet.
I have seen somewhere that 10.4 has some problems reporting PCI cards accurately.

Cheers
Andy
