Hi all,
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.
