I Only See One CPU
 
I have a PC right now that is a SMP (Dual CPU) machine running dual AMD Opteron 246 HE CPU's but after a fresh install this weekend, I noticed that both top (htop) and KDE only see the system as having one single processor and I don't know if this is a limitation of the default kernel it has installed or perhaps something else.

Code:
# cat cpuinfo
processor      : 0
vendor_id      : AuthenticAMD
cpu family      : 15
model          : 5
model name      : AMD Opteron(tm) Processor 246 HE
stepping        : 10
cpu MHz        : 2009.296
cache size      : 1024 KB
fdiv_bug        : no
hlt_bug        : no
f00f_bug        : no
coma_bug        : no
fpu            : yes
fpu_exception  : yes
cpuid level    : 1
wp              : yes
flags          : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow ts fid vid ttp
bogomips        : 4020.95
I don't see "processor: 1" where it would normally be below the 1st one labeled "0".

When I run "top or htop" there is only one single cpu as well.

What should I check or do...?

Using the 2.6.18-4-486 kernel.

Perhaps it is the kernel that is installed. A kernel that says -486 would be suspicious to me.

Hope this helps

Yes - I installed the 686 kernel and now I can see both CPU's and the system seems a bit faster.
