Since this is National Kernel Day, I have a question. No, 2 questions:
I'm running an Asus A7N8X Deluxe ver 2 m/b with an AMD processor:
[root at mavis ~]# cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 6
model : 10
model name : AMD Athlon(tm) XP 2600+
stepping : 0
cpu MHz : 1912.933
cache size : 512 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 mtrr pge
mca cmov patpse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow
bogomips : 3776.51
For some reason, Anaconda thinks I need an smp kernel. This is a
wrong-headed notion that showed up in FC1 and continued to FC2, FC3 and
CentOS 4. It always installs both kernels, making -smp the default
which I have to change to non-smp for ntpd to work right (Gives
off-the-chart jitter, never syncs, etc). I have read in one place or
another that:
1. It's O.K. to run an smp kernel on a single-processor machine
2. The installer picks the smp kernel if the cpu flag "ht" is set --
which mine isn't.
So, can anyone explain why, on a fresh bare-metal install I'm blessed
with an smp kernel? Also, is the statement about an smp kernel running
O.K. on a single processor machine pure hogwash or is there something
goofy about my m/b and/or processor?
Of course, once there is an -smp kernel installed "yum update kernel*"
keeps the string of luck going.

It's good to know I'm not alone. Frankly, I'm amazed at the number of CORRECT guesses made during installation. BTW, apologies for the HTML in my previous post.
