Porting linux to Stellaris Cortex-M3

Hello everybody,

I'm currently porting linux to a Stellaris board from TI.
But I'm having some problems with the execution of the Busybox init program.

Some info:
- the toolchain is CodeSourcery lite edition
- I've followed the steps described by Catalin Marinas at
http://www.linux-arm.org/LinuxKernel/LinuxM3
- I'm using my own bootloader, based on the script at the site above
and on informations found on linux/Documents
- I've based the mach-stellaris implementation from realview and mps ones
- the timer, irqs and uart seems to work fine
- the system crashes after calling /init, which is linked with Busybox init
- BUG: scheduling while atomic: init/1/0xffff000a

Any idea?

Best regards,
Fernando Akira Endo
