>Description:
I'm having trouble using Orinoco Silver a/b/g combo pcmcia card on Dell Latitude D620.

It happens in following order:
1. First I reboot FreeBSD-7.0 laptop with Orinoco combo card plugged in.
2. Then when I try to unplug the card it panics.

However after rebooting (without plugged in card)
when I try to plug in and unplug the card everything is fine, no crash.

System I have:

devil# uname -an
FreeBSD devil.micom.mng.net 7.0-PRERELEASE FreeBSD 7.0-PRERELEASE #3: Tue Feb  5 10:29:24 ULAT 2008     tsgan at devil.micom.mng.net:/usr/obj/usr/src/sys/DEVIL  i386

When panics, on the serial console it shows:

.
