Well, what struck me by surprise is when a very similar thing happened on my laptop, which only runs FreeBSD.... In my case, it happened when I set up my normal -CURRENT slice to run a kernel based on NEWCARD, then tried a reboot back to -STABLE (different slice of the disk). I found that power-cycling the card itself (whether via pccardc or eject/insert) didn't do the job, but power-cycling the laptop itself seems to be sufficient (and, evidently, necessary). The card in question is a Cisco 340 Series 802.11b NIC. (I tried an Intel CE3 (xe driver, under -STABLE), but my -CURRENT kernel didn't seem to recognize it. I'll see about looking into this in more detail today.) I thought the behavior odd when I noticed it first 2 days ago; yesterday, after building that day's -CURRENT, it happened again. I rather expect it to happen today, after I build today's -CURRENT.... Anyhow, seeing the behavior in question occur with a switch between OSs for which the sources are available may provide enough additional information to better understand the mechanism in question.
