Thanks a lot, can you tell me what it said early in bootup?
Specifically this part:
[ 0.000000] PAGE_OFFSET is 0xffff800000000000 (max_phys_bits = 47)
Thanks again!

This is a T4-1 in CA. I'll push it hard.
[ 0.000000] PAGE_OFFSET is 0xffff800000000000 (max_phys_bits = 47)
Locally I try not to wear noise suppressing head phones on Saturdays for
my T4-2 :) I will review the patches again by tomorrow. They look good so far!
thanx,
bob

I sent you email and ran away from my sparc right after that.
I'll send everything tomorrow!
