I sporadically get this crash while running "arp" under both 2.5.46
and 2.5.47.

ksymoops 2.4.6 on i586 2.5.47. Options used
     -v /usr/src/linux/vmlinux (specified)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.5.47/ (default)
     -m /usr/src/linux/System.map (default)
