KACE Product Support

I have read as much material as would seem relavent to this, but I am still stuck.  The media manager seems to create the image source without issue and I am uploading media that I can boot from a usb thumb drive.  The iMac is brand new, 10.8.4.  I can see the Netboot image in the startup, by pressing alt at boot, etc., netboot enabled on K2000, boot environment is selected on the general settings page, DHCP is coming from the k2000 itself.  I can select the netboot, the world starts spinning, but then it crashes the iMac.

Here's the first page of the crash report:
