Red Hat Bugzilla – Bug 100900
anaconda thinks Intel D875PBZ is a multiprocessor board
Last modified: 2007-04-18 12:56:10 EDT
Description of problem:
After installing on an Intel D875PBZ board, anaconda has installed the SMP
kernel in addition to the uniprocessor kernel. This is a uniprocessor board.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install SEVERN on a system that has an Intel D875PBZ board.
Both the uniprocessor and SMP kernels are installed.
Only the uniprocessor kernel should be installed.
Here is the link to information about this board on Intel's site:
This problem happened with RedHat 9 as well, but I didn't report it since the
board came out after RedHat 9 had already been released. I don't have access to
a SEVERN machine with this board, but I am attaching the /etc/sysconfig/hwconf
file from a machine with this board that is running RedHat 9 in case that
provides any useful information. Please let me know if there is any other
information that would be useful.

Doesn't this have a processor which utilizes hyperthreading, though? If so,
Yes, it does. Is this correct behavior? Should I be using an SMP kernel on a
uniprocessor machine with hyperthreading, or is the install software incorrectly
using this as an indicator?
Then the SMP kernel is correct. Hyperthreading provides both a physical and
logical CPU to the OS -- to take advantage of both, you have to use an SMP kernel.
