unloading wireless adapter - system hang

[Gregor Ibic]

I have a RH 7.1 (2.4.2 kernel) and RoamAbout PCMCIA cards and
PCI to PCMCIA bridges (TI1410 chip).

I installed precompiled drivers from Enterasys and I can succesfully load
the pcmcia and driver.

status from iwconfig:
eth1      RoamAbout 802.11  Channel:3  
          Link Quality:0/92  Signal level:-102 dBm  Noise level:-102 dBm
          Rx invalid nwid:0  invalid crypt:0  invalid misc:0


But when I try to unload the interface
/sbin/ifconfig eth1 down

the system freezes realy hard.

I have to press the RESET button.

Is there any way to solve this problem?

Regards,
Gregor
