I'm receiving a recurring kernel oops on a machine running sid and
2.4.18. The oops and ksymoops output are below. This particular oops
occurred after running dmesg. I am new to oops tracing. Should I join
the kernel mailing list and post it there? Could this just be something
like bad RAM?
Thanks.
ksymoops 2.4.5 on i686 2.4.18. Options used
-v /usr/src/linux/vmlinux (specified)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.18/ (default)
-m /boot/System.map-2.4.18 (default)
