I got the following oops with 2.4.5-ac12 after I issued "rmmod -a" twice. I only notices the oops after I issued "rmmod -a" once which might explan that ksymoops cannot name the module which caused the oops. This is possibly ALSA-related (although I never had problems with unloading alsa modules befode). Walter WARNING: This version of ksymoops is obsolete. WARNING: The current version can be obtained from ftp://ftp.ocs.com.au/pub/ksymoops Options used: -V (default) -o /lib/modules/2.4.5-ac12/ (default) -k /proc/ksyms (default) -l /proc/modules (default) -m /usr/src/linux/System.map (default) -c 1 (default) 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.
