You need to make sure you're running the same machine with qemu and gem5. Make sure that you've set the --machine-type= to the appropriate machine. Kernels aren't compatible between different variants as the memory maps can be completely different. I don't know what platform you've compiled your kernel for but it needs to be something we've got in gem5 (RealViewPBX, or VersatileExpress EMM). If the kernel you're building has a bootloader emebedded in it, you'll need to specified the --bare-metal command line option, so that the simulation doesn't do initializations for the kernel that the bootloader will already do.
