Actually it doesn't.  For some reason, I now hit the following ICE with
3.4.6 (Debian's `gcc-3.4', version 3.4.6-2) systematically:

    CC      fs/proc/proc_misc.o

  see <URL:file:///usr/share/doc/gcc-3.4/README.Bugs>.

I finally used 3.3.6 to built the whole kernel and I don't hit any ICE
there.  Is anybody building SPARC kernels with 3.4 or 4.x?

The kernel (once cleanly recompiled with 3.3.6) still hangs at the same
point, whether there are one or two CPUs in the machine.

I guess I should try to selectively revert some of the SMP patches in
order to try to find out what's causing this.  Any advice about how to
proceed?

Thanks,
Ludovic.
