I'm a little curious about the fact that the address this occurred at is 
0xc0003858, which suggests it's kernel code. As Philippe asked, what version 
of the ipipe are you using? Also, what is your exact CPU? The e300c2 does not 
have an FPU, so this would be quite a configuration problem.

Are you using any kernel threads that use the FPU?
