RE: SMP in 32-bit arch/powerpc

Do you have more detailed descriptions? Our MPC8641D(dual-7448 core CPU)
board works well.

Is anybody else having problems with 32-bit SMP support in=20
arch/powerpc?
I'm using 2.6.17 as my current base, because I've not yet merged the
latest mpic changes.

I'm currently bringing up a dual-7448 board, and when I build=20
the kernel
with CONFIG_SMP, the bootmem allocator corrupts the device tree. The
strange thing is, this still happens when I don't start the=20
second CPU.
Kernels built without CONFIG_SMP run flawlessly on the same hardware.
