SMP issues on K8S Pro S2882G3NR

[Cassidy B. Larson]

Hello,

We just got our new Dual Opteron 246 box and I'm having some problems getting
our second CPU to load correctly with a SMP kernel.

Wondering if anybody could offer some assistance, or pointers.

Using the Tyan K8S Pro S2882G3NR board. 3ware 8506 4 port SATA card. 

I've also tried Disabling ACPI in the kernel and bios, then one at a time.

Below are partial dmesg, mptable and kern config.   Unfortunately, with
different combinations of the NO_MIXED_MODE on and off and acpi enabled and
disabled, I am unable to get SMP to launch our second CPU for use. 

Anybody experienced the same problem?? Would -CURRENT be ideal over 5.2.1-p4 for
me?  Note that the GENERICicized SMP kernel also does not launch the second
processor.

Any pointers, helpful hints, etc? 

Thanks,

-c

mptable processors entry:

MP Config Base Table Entries:

                 0       0x10    BSP, usable     15      5       8

0x78bfbff

So I see that mptable seems to see both processors, am I assuming correct here?
