Hey Jouni

Here is what i did.I tried 5.0 V (COMPAQ WL11 card) with orinoco.o driver, 
it worked, just fine.

But when i tried to put , NOT the same card but 5.0 V LINKSYS WPC11 card 
with hostap_cs.o using this:

modprobe hostap
modprobe hostap_cs ignore_cis_vcc=1(just to play safe)

I see modules are loaded:

here is the dmesg :

NO WLAN0 Device registered. if i do 'iwconfig' IT JUST HANGS after this:

[root at localhost root]# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

Warning: Driver for device wifi0 has been compiled with version 14
of Wireless Extension, while this program is using version 15.
Some things may be broken...

CUD NOT ABLE TO DO ANYTHING AFTER THIS, I HAVE TO RESTART THE SYSTEM
cardctl eject command will not even work.
( I am sending this email from some other computer)
---------------------------------
I DID THE SAME PROCEDURE WITH NETGEAR 5.0 V PCMCIA card with same results.
---------------------------------
NOW i tried to load the 3.3V card (Senao NL2511)

modprobe hostap
modprobe hostap_cs ignore_cis_vcc=1

hostap_cs: 0.2.2 - 2004-05-31 (Jouni Malinen <jkmaline at cc.hut.fi>)
hostap_cs: setting Vcc=33 (constant)

==>NO SPURIOUS IRQ7 HERE<==

wifi0: STA: id=0x1f v1.4.9

Host AP mode WDS

BUT if i do iwconfig    after this : it just HANGS.
------------------------------------
All i can do at this point is to restart the system.

i looked into my /etc/pcmcia/config.opts file and the IRQ 7 is excluded , i 
also excluded IRQ from it.
and other which are excluded by default.

i do not know how should i make this working. I believe there is something 
to do with the IRQ problem. As i also read your conversation earlier on 
SPURIOUS IRQ 7 with jun.


I hope i am more clear this time on what i am doing. All these cards which i 
tested above work fine with my laptop.

I will appreciate some useful hints and the direction to move forward. Also 
just to mention if i start 'cardmgr' instead of loading modules using 
'modprobe' system just hangs.

I will be looking forward to some quick response.
