no SMP

no SMP

[reiner.funck]

Dear Sirs,

I ask you for an advice. I get with all kernels (2.6, 3.1, ... 3.4) with all
distributions (suse, ubuntu, ...) in the system messages
....
                                                  CPU: Physical Processor ID:0

I work with Asus Mainboard M5A99X EVO and AMD FX(tm) 8150 (eight core) 
processor. The Bios
Version is the newest (1208, used with default options). The Results are equal 
with Kernel
option acpi=off or on, maxcpus=8 or not..
Systemmonitoring shows one CPU.
Bios must have the missing information? (weird, boot CPU (#16) not listed by 
the BIOS).
Asus replied to my question: we test no Linux systems (windows7 works with 8 
cores).
Do you have an advice for me?

Yours faithfully

Hmm, fun. Can you boot any kernel on your system successfully? If so,
can you send full dmesg from it?

Also, is it a 32-bit or a 64-bit kernel?

Also, can you test booting with "numa=off"?

Thanks.
