This is 2.4.0-test7-pre4 slightly patched by http://www.moses.uklinux.net/patches/linux-vxfs-2.4.0-test7-pre4.patch (the patch is irrelevant to the oops but I list for completeness) I was mkfs'ing a new filesystem on a 61G disk partition. Oops is interesting (the fact that mkfs is actually mkfs.vxfs is totally irrelevant - think of it as "some app" which writes some stuff to /dev/hdd1). Regards, Tigran ksymoops 0.7c on i686 2.4.0-test7. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.0-test7/ (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.
