Hi Joakim,

Things look much better with this patch set, I see none
of the random crashes that I had with the earlier patches.
I'll leave it running on a few boards here over the weekend and
see if anything bad happens. 

Since patch #1 fixes a regression in the current kernel
is there any way you can get that into .32? I know it is late,
but without that patch .32 doesn't work for 8xx boards.

On another note, how does your patch set affect performance?
Have you been able to do any testing?  What is the advantage
of using dcbX in the kernel, besides keeping the code
similar to other ppc platforms?  Maybe it is good to
catch/fixup userspace uses of dcbX, but why change the
kernel? How does it affect performance?

thanks!
/rex.
