RE: Custom Kernel doesn't recognize 2nd CPU
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
debian# cat /proc/cpuinfo
cpu : TI UltraSparc II (BlackBird)
fpu : UltraSparc II integrated FPU
promlib : Version 3 Revision 17
prom : 3.17.0

ncpus probed : 2 <<<Good
ncpus active : 1 <<<What's this???
Cpu0Bogo : 897.84

Kernel is SMP:
debian# uname -a

Ideas? Is there any other info I can supply?
