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): 9.0.93 How reproducible: always 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: http://www.intel.com/design/motherbd/bz/index.htm?iid=ipp_browse+motherbd_d875pbz 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.
Created attachment 93166 [details] /etc/sysconfig/hwconf from RedHat 9 system with D875PBZ board
Doesn't this have a processor which utilizes hyperthreading, though? If so, that's why.
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.
