Description Jay Berkenbilt 2003-07-26 22:09:12 UTC
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):


How reproducible:


Steps to Reproduce:
1. Install SEVERN on a system that has an Intel D875PBZ board.
Actual results:

Both the uniprocessor and SMP kernels are installed.

Expected results:

Only the uniprocessor kernel should be installed.

Additional info:

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,
that's why.

Comment 3 Jay Berkenbilt 2003-07-27 15:13:44 UTC
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?

Comment 4 Jeremy Katz 2003-07-28 15:57:22 UTC
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.
