Hello all,

I've got a little problem here with my network card (cardbus) - using the 
Vortex driver after I've entered suspend on my laptop (dell latitude) and 
revive the machine from it.

After reviving the machine, the dulplex mode and mbits are wrongly 
autodetected. I'm connected to a 100mbit/FD network, and the card goes back 
to the default state of 10mbit/HD.  Disconnecting/reconnecting the cable does 
not help. 

If I remove the module from the kernel, and re-load it, the system hangs 
solid.

After reviving the pc also 'stalls' now and again, approximatively every 15-20 
seconds, for 1-2 seconds.

In my kernel logs i get these messages:

over and over again (with different numbers), until i reboot the machine. 
Networkconnection never gets established.
