Hi!
A kernel 2.6.39 doesn't boot on my POWER MAC G4.

Same problem with my dual-G4 MDD. A few more infos:
The machine hangs just after the message "Returning from prom_init" (still
in the OF screen).
The kernel works fine with the option maxcpus=1, but it locks up as soon as
I try to enable the second CPU with echo 1 > /sys.../online.

I just verified that current upstream 3.0-rc1+ does boot fine.

The fix is:

  c560bbceaf6b06e52f1ef20131b76a3fdc0a2c19
  powerpc/4xx: Fix regression in SMP on 476
[...]

Yes, that patch fixed the problem. Thanks.
