Interesting thing, I noticed this same behavior with my first build this evening, and it turned out to be the ATI video board I was using. I thought it was a supported 4500, but this particular cheapo HIS ATI board just simply caused a panic with ATI or supported iboot. I noticed the same IOUSB errors on the screen when booting, but it turned out to have nothing to do with my issue. The panic for me was caused by a PCIe SLOT 1 error, and the text in verbose would freeze at the point of panic and just maybe 10 lines up from the system uptime message was the cause of the kernel panic. I just happened to have an nvidia 8600gt in my living room media center. I popped that into the system and had no trouble loading vanilla MacOS with iboot supported after that. I'm using the GA-P55A-UD3 with bios version F9, Core I5 750.GeneralAntilles said:Downloaded and burnt the 6/15/10 iBoot 2.0 ATI to a CD on one of my old G5s.
Set BIOS to optimized defaults, HPET 64-bit, AHCI, CDROM first boot device.
Placed iBoot ATI CD in drive, reboot.
Remove iBoot CD, place Retail 10.6.3 CD in drive, hit F5.
Boot from Retail CD.
Kernel panic after about 5 minutes of gray Apple.
