This looks like the bootup code for gen f Opterons. It doesn't look like the h8dme has a fam10 variant yet, which is what you need for the 2378 CPUs.
Thanks Arne! I'll have to figure out how to proceed from here.
On a side note, it _looks_ like the slowdown might be due to the udelay unification. Still bisecting.
I'm surprised you found a revision that works, since it has never supported fam10. I think it would be more fruitful for you to look at one of the boards that has both fam10 and k8 support, and try to put together an h8dme_fam10 port.
For the record, I've been trying to get that going for a while, but have not had much success - very early hangs in the fam10 code on this board. Cf. the problems Knut is having, I think...
Thanks, Ward.
