RE: Custom Kernel doesn't recognize 2nd CPU

["Small, Jim" <jim.small@eds.com>]

Good point David, I forgot to include that...

Walking through boot up:

>>>We see that OBP sees both CPUS:<<<
Sun Ultra 60 UPA/PCI (2 X UltraSPARC-II 450MHz), No Keyboard
OpenBoot 3.17, 2048 MB memory installed, Serial #11419681.
Ethernet address 8:0:20:ae:40:21, Host ID: 80ae4021.

<...>
>>>So far, so good...<<<
Found CPU 0 (node=f006d3b4,mid=0)
Found CPU 1 (node=f006d720,mid=2)
Found 2 CPU prom device tree node(s).
Entering UltraSMPenguin Mode...

>>>Uh oh, what's this???<<<
Error: only one processor found.
Waiting on wait_init_idle (map = 0x0)
All processors have done init_idle


And finally:
debian#  cat /proc/cpuinfo
cpu             : TI UltraSparc II  (BlackBird)
fpu             : UltraSparc II integrated FPU
promlib         : Version 3 Revision 17
prom            : 3.17.0
type            : sun4u
ncpus probed    : 2  <<<Good
ncpus active    : 1  <<<What's this???
Cpu0Bogo        : 897.84
Cpu0ClkTck      : 000000001ad2b820
MMU Type        : Spitfire
State:
CPU0:           online

Kernel is SMP:
debian#  uname -a
Linux debian 2.4.25 #2 SMP Mon Mar 8 09:21:12 EST 2004 sparc64 GNU/Linux


Ideas?  Is there any other info I can supply?
