Your kernel is probably writing some undefined mode in
the CPSR.  Most implementations will translate that to
another valid mode, qemu doesn't.

Thanks Laurent

ARM Linux kernel is built with arm-gnu-eabi  cross  compiler toolchain (from code sourcery).

I dont think this will be a problem (correct me if i am wrong). It creates normal zImage as well as uImage (with the help of mkimage )

Can you please brief the point "Most implementations will translate that to another valid mode, qemu does n't"

Can you please  suggest any other options to test/debug my basic linux kernel image as I dont have the real hardware yet.
