Description Johnray Fuller 2005-11-22 21:30:16 UTC 
Description of problem:

At this URL the kernel-SMP statement is confusing:

http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/ch-kernel.html

It states:

"kernel-smp รข Contains the kernel for multi-processor systems. The following are
the key features:

    *      Multi-processor support
    *      Support for more than 4 GB of RAM (up to 32 GB for x86)

      Note
       	
      Although kernel-smp supports up to 32 GB for x86 architectures, Red Hat
recommends use of kernel-hugemem for memory configurations higher than 16 GB."

Second bullet point needs to read:

Support for more than 4 GB of RAM (up to 16 GB for x86)

The NOTE needs to be changed to the following:

"Although kernel-smp theoretically supports up to 32 GB for 32 bit x86
architectures, Red Hat will not support the use of more than 16 GB of RAM. Use
of kernel-hugemem is required for memory configurations higher than 16 GB."
