3Com pcmcia wlan with 2.6.0-test8

3Com pcmcia wlan with 2.6.0-test8

[Mathias Fröhlich]

I use a 3Com 3CRSHPW196 PCMCIA wlan card with the atmel_cs module on a IBM R40 
laptop. Installed is Fedora 0.95 together with linux 2.6.0-test8.

The firmware is loaded using the kernel-hotplug firmware loader.

When the device is stopped or unloaded i get this message:

unregister_netdevice: waiting for eth1 to become free. Usage count = 4

Sometimes this locks shutdown hard. Sometimes the pcmcia card is left more or 
less unusable. It is afterwards not detected on bootup and also not on 
insertation past pcmcia initialization. Only

cardctl insert

switches the LED on the card on. Sometimes it is then usable, sometimes not. 
The first 2.6.0 boot past a session with linux-2.4.22 using the pcmf502r3.o 
module is allways successful as far as I remember.

Could you please take a look at the atmel driver?

    Thank you in advance

I have experienced the same behavior while playing with APM/ACPI
suspend. It seems my machine gets frozen when trying to suspend with
CardBus/USB modules loaded, so I usually unload them before suspending.
Sometimes, I have seen the kernel complaining while unloading 3c59x with
an usage count greater than 1, which is impossible, since I do only have
a network card on my laptop and it's the 3Com.
