Kernel 2.4.21 oopses with Atmel USB driver

Hi all,
I am currently setting up a ThinClient based on a VIA C3 800Mhz.
The Linux distro is home made (Linux From Scratch) based on a kernel
2.4.21. The goal of this system is to connect to a server through
a D-Link DWL-900AP+ Access Point. The thinclient has a built-in
Realtek NIC (RTL-8139) and a Wireless USB card based on the Atmel
AT76C503a chipset (USB id = 03eb:7605).
The problem I encounter is a Kernel oops on the thinclient
when I set up manually the SSID or when I scan the network (the AP does
not broadcast the SSID). I mainly use lvnet and sometimes iwconfig.
In order to facilitate the testing, there is no WEP encryption, no MAC
filter (see details below).
As soon as the AP broadcasts the SSID, the thinclient sets up
automatically the SSID and as from that moment, it is very stable
(Thinclient joins the network, communication is good, no crash).
I tried the latest official release (2.1.2.2) and
the latest snapshot (20030613) but the behavior is the same.
For your information, I am a beginner in the WiFi world. So, if there
is something I am doing wrong, please let me know.
Could check this and help me solve this problem ?
Thanks in advance.
Please find below all the technical information :
