Subject: Oops in 2.4.0-test10-pre6
Sender: linux-kernel-owner@vger.kernel.org

Hi!

This oops is not a new one .. I've it for quite a long time.
It always happens when starting a hamradio program called 'ulistd'.
There is not any problem at all with this program and the 2.2.17 or 2.2.18prex
The system is frozen. I can access the 'magic keys'.


My configuration is Pentium 200MMX / 64Mb SDRAM with :
------------------------------------------------------
Linux debian-f5ibh 2.4.0-test10 #1 ven oct 27 14:11:33 CEST 2000 i586 unknown

This is the raw oops :

And this is the oops processed by ksymoops :
--------------------------------------------
ksymoops 2.3.4 on i586 2.4.0-test10.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test10/ (default)
     -m /boot/System.map-2.4.0-test10 (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.
