I guess Philippe was talking about the nanoMIPS here.

By the way, ppc405 is not on an optimal shape yet for sure, but we are 
getting better and better, and I'm aiming at getting it back to work, 
just because I need it.

By the way, were you able to re-test with CONFIG_MATH_EMULATION enabled 
after your last oops report which shows that you're trying to execute 
floating points instruction ?

Thanks
