With "Xircom", "CardBus Ethernet 10/100 + Modem 56", "CBEM56G", "1.03"
in PCMCIA slot, do a "cardctl eject". You will then get a Segmentation 
violation.

Reproducible: Sometimes
Steps to Reproduce:
1.Use PCMCIA card for a day or two without interruption
2.Shut down Ethernet or PPP
3.Do "cardctl eject"
	

Actual Results:  Segmentation violation. The card is from now on reported
as being
busy. /etc/rc.d/init.d/pcmcia restart doesn't help. As far as I have
figurred it out, I have to do a full reboot to get things back to its
normal usable state.

Expected Results:  Card should have freed and kernel resources for it put
in idle state for standby mode.

I'm using kernel-pcmcia-cs-2.2.17-14 and kernel-2.2.17-14 on a Dell
Inspiron 7500 laptop with a 650 MHz i686 and 256 MByte memory and 18 GByte
disk. All RedHat-7.0 updates have been applied. I'm using AcceleratedX-6.0
from XiGraphics as X server.
