I wanted to just give 2.6.18 a spin and I tripped over something I
didn't expect.

cpu_up: attempt to bring up CPU 4 failed
kfree_debugcheck: bad ptr c15f6000h.

This box was booting 2.6.18-rc6-mm2 with some help just fine. There
are a few outstanding issues but I know about them already. This looks
to be something else.

I haven't booted a non-mm tree on this box in a while (but I know
2.6.17 worked). Is this something all all ready sorted out and soon to
be pushed upstream?

Thanks,
Keith
