Dear,

Having installed a RedHat 7.1 distro on a ASUS CUV4X-DLS based system 
(no install problem), the smp boot fails, the last lines displayed are 
the following :

----- cut-here ---------------
testing the IO APIC .........................................

  WARNING : unexpected IO-APIC, please mail
          to linux-smp@vger.kernel.org

.............................. done.
Calibrating APIC timer .......
  CPU clock speed is 1004.6578 MHz
  Host bus speed is 133.9542 MHz
CPU0<T0:1339536,T1:893008,D:14,S:446514,C:1339542>
----- cut-here ---------------

The MB is equipped with two PIII 1 GHz and 256 MB of ECC 
registered/unbuffered PC133 SDRAM. The board, the cpus, the memory and 
just about everything else on these machines (I have six of them) have 
run Windows 2000 Prof. since they were built beginning of march 2001.

As far as I know it is a VIA chipset of some kind.
When booting "linux-uniprocessor", the system seems to run perfectly. 
I'm using it to write you this message.

As far as I know the kernel is a 2.4.2. I may test with a 2.4.5, but 
would just need a pointer to some documentation on how to switch my 
kernel correctly.

I'm a C/C++ developer, has written device-drivers for Windows 2000, but 
with very few linux experience.
