Illegal Opcode Red Screen after SLES10 SP3 unattended installation

[sdrake48]

After reboot that occurs during unattended installation of SLES10 SP3, get red screen with Illegal Opcode error when trying to boot from hard disk (72gb sas attached to internal 410i). Using usb stick for autoinst.xml. Removing the stick and rebooting gives a different msg - Booting from local disk...No Operating System. Booted the SP3 DVD into Rescue and tried running grub - but 'root (hdx,y)' finds no hard disk. Tried every possible x and y.
I'm using the autoinst.xml file created by SLES10 during a manual install of SP3 on the same server.
Anyone have any success with unattended SLES10 SP3 installation on any G6 server? P.S. I have the integrated quad nic removed and no additional pcie cards (except the sas expander card).

Problem only occurs when using usb stick (/dev/sda) for autoinst.xml file. Works ok from usb diskette drive.
