 I can confirm both the originally-reported problem (i386 cd boot fails, 
 amd64 cd boot succeeds) on my newly-built system with a Gigabyte 
 GA-H67-USB3-B3 motherboard, and the workaround:  if I switch the SATA 
 controller to IDE mode from AHCI in the BIOS, it boots OK under i386.
 
 When it hangs, it then panics somewhere in USB as soon as I hit a key on 
 the USB keyboard.
