Subjecthelp me understand /var/log/dmesg , source code traverse
Date
This is the first time i have complied a new kernel .Previously i had
installed from cd redhat6.2 .Compliled 2.4.0-test5 kernel and saw a
different /var/log/dmesg .
1.Help me figuring what each of these lines say ?
2.Are there any command line html veiwers to traverse the documemtation ?
3.Are there any applications which help in browsing thru the source code ?
Though there is too much to scroll, Any help in this regard would be
acknowledged .
