>Number: 5918 >Category: kern >Synopsis: kernel reports wrong CPU MHz >Confidential: no >Severity: non-critical >Priority: medium >Responsible: freebsd-bugs >State: open >Quarter: >Keywords: >Date-Required: >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Wed Mar 4 17:00:01 PST 1998 >Last-Modified: >Originator: Brian Feldman >Organization: none >Release: FreeBSD 3.0-CURRENT i386 >Environment: This is a FreeBSD 3.0-CURRENT machine, which is cvsupped daily. It runs on a EIDE hard drive, has 80 MB RAM, and runs a ~210 MHz overclocked K6-200 CPU. >Description: Since only recently, the kernel will report the wrong speed of the CPU (0.00 MHz). This does not seem to have any affect anything but the actual printing of the CPU speed. dmesg: Copyright (c) 1992-1998 FreeBSD Inc.
