Booting multiple instances of L4 Linux

Hello, I'm trying to boot 2 instances of L4 linux on top of Fiasco.OC micro kernel but I get an error during the checksum verification. I tried to boot a L4Linux and a hello, it was ok but not with 2 L4Linux. I would like to boot 2 l4Linux on a Beagleboard emulated by QEMU (The error is not from QEMU) The output is: " Verifying Checksum ... Bad Data CRC ERROR: Can't get kernel image!" Is it an error from my module.list file? My config file?..Any ideas? Thank you, Best regards. Julien.
