I've attached the file I hand wrote for the oops, which I then fed to ksymoops. Also attached again is the output from ksymoops. If something is inconsistent, and I need to regen the output with ksymoops and my System.map, could someone be so kind as to suggest a proper commandline? I used: ksymoops -K -L -o /lib/modules/2.4.4/ -m /boot/System.map-2.4.4 < oops.txt >ksymresult.out Reformatted for mail, originally one line. Nothing ever made it to /var/log/ksymoops.
