Description of problem:
When running tux as an ftp server, client connections are successful.
However when a directory list is requested, the host tux is running on
has a kernel panic. A 'get' also results in kernel panic. Other
commands such as 'rhelp' do not result a kernel panic, with the server
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install tux
2. Start tux - service tux start
3. As per the supplied documentation, set tux to do both http and ftp:
echo "http://0.0.0.0:80" > /proc/net/tux/0/listen/0
echo "ftp://0.0.0.0:21" > /proc/net/tux/0/listen/1
service tux restart
4. Using any ftp client, connect to server, try 'ls, dir or get' ftp
Actual Results: ftp command fails and kernel panics
Expected Results: ftp commands from client sent to server, server
responds to client, and kernel remains calm.
I have been running on a single hyperthreading Pentium 4 processor.
Using either SMP or uni-processor kernel results in the same kernel panic.
Have confirmed that problem occurs when running these kernels (UP or SMP):
Also have found that a Red Hat Enterprise 4 (Beta) installation
running kernel 2.6 does not have the problem.
Am currently unable to use netdump, as my network card is not supported.
I will try to setup a serial connection to grab a kernel dump if
requested. A sysreport is ready if it is needed.

Screendump of the crash. The double fault means that the user hasn't been able
to gather any dumps or other logs.
the FTP server is disabled by default (it was devel code in RHEL3 and is not
supported), so i'm closing this bug with WONTFIX. It works in RHEL4.
