I'd like to resubmit yesterday's problem report, this time with the
necessary information included (Thanks Dan!).
Thanks in advance!
Frederik
1. When running netstat -a, the kernel panics (not always, but easily
reproducable)
2. I'm experiencing frequent kernel panics, when doing netstat -a. This
is as a regular user.I recompiled my 2.4.19 kernel with serial console
support earlier, which seemed to have removed the problem. Not so.
3. kernel panic; netstat
4. Linux version 2.4.19 (root@maui) (gcc version 2.95.4 20011002 (Debian
prerelease)) #1 Sat Dec 28 20:55:03 CET 2002
5. Output of ksymoops:
ksymoops 2.4.6 on i686 2.4.19. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19/ (default)
-m /boot/System.map-2.4.19 (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.
