I have included a copy of my kernel config which is extensivly, though not totaly, commented. >How-To-Repeat: Not applicable, though to understand the problem you need to hav tried to produce a realy leen kernel. >Fix: # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # For more information read the handbook part System Administration -> # Configuring the FreeBSD Kernel -> The Configuration File. # The handbook is available in /usr/share/doc/handbook or online as # latest version from the FreeBSD World Wide Web server # <URL:http://www.FreeBSD.ORG/>; # # An exhaustive list of options and more detailed explanations of the # device lines is present in the ./LINT configuration file.
