I'm confused now :-)  So does gcc-4.1.3 produce the bad kernels or does
gcc-4.3.2?

I built Linus's current tree under Lenny and that booted up perfectly
on my Niagara2 box.

Also, please increase CONFIG_NR_CPUS to 256 in your SMP builds on sparc64
in Debian.  I'm missing most of my cpus with the Debian built kernels :-)

Probably I've mentioned this before :-)
