Hi, Pete and All. I sent this to David Brownell earlier today. Initially, I didn't have ksymoops installed, but I got it installed and ran the oops through it. Below are the results of it. Thanks for the replies, I'll take a look at Pete's link right now. Brad [root@murray-1-1 /root]# ksymoops <oops.txt ksymoops 2.4.1 on i586 2.4.3. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.3/ (default) -m /usr/src/linux/System.map (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
