| |
Hi,
Can I be cc'ed at lmcdgor@lmc.ericsson.se (as per a normal reply) ? Thank you.
Included at the end is the ksymoops output after the crash (one of them anyhow :-)
My setup involves 2 PII installed with Linux RedHat 7.0 and 2.4.4 kernel with IPv6 enabled: CONFIG_EXPERIMENTAL=y CONFIG_IPV6=y CONFIG_IPV6_EUI64=y CONFIG_IPV6_NO_PB=y
Also, the following application web servers were installed (enabled for IPv6) : Jigsaw 2.2.0 Tomcat 3.2.1 Apache 1.3.19
To enable IPv6 with the Java based web servers, I used jipsy 0.2.1. Lastly, netkit 0.5.1 was installed containing in particular ping6 utility.
To reproduce the crash, I ping6'ed one machine from the other in command-line mode, no servers running. That's it. Originally, the first crash occurred in a X server environment while querying the web servers in IPv6.
Thank you,
David Gordon Ericsson Research
Here's the output: **************
ksymoops 2.3.4 on i686 2.4.4. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.4/ (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.
No modules in ksyms, skipping objects Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file? Warning (compare_maps): ksyms_base symbol __VERSIONED_SYMBOL(shmem_file_setup) not found in System.map.
