Hi Alex,

Current 2.6 kernels are doing pretty well for me. There are issues, though. You
will want to move all your memory to the bank of cpu0 if you can. Linux won't
see all of it no matter where you put it, but you get more if it is all on one
cpu. Make sure you have a current OBP, I'm running 4.17.1.

I can't even get 2.4 to userland.

Linux v240 2.6.15-gentoo-r7 #1 SMP Fri Mar 3 12:40:28 CST 2006 sparc64 sun4u TI
UltraSparc IIIi (Jalapeno) GNU/Linux
