Synopsis: after a fresh boot, ran "accton" with no arguments. It died
with a segmentation violation, and generated an "oops".

Here's the ksymoops output. Since this involves the libc acct() function,
you'll probably be interested in the C library version as well: 2.2.3.
Compiler is "gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)".

====--CUT HERE--====
ksymoops 2.4.5 on i586 2.5.7. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.7/ (default)
-m /usr/src/linux/ (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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
