Your Orinoco card seemed to have sent a broadcast data frame that the
Host AP driver dropped since it was adhoc frame. This should not cause
such problems that you described. Something set wlan0 interface down
after this. I don't think there is any code in Host AP driver that could
do this, so I would assume that it was some unknown user space program.
How do you configure IP addresses for wlan0 and eth1? Could you have,
e.g., DHCP client in the background setting interfaces down after some

Setting the interface down will remove all routing entries using that
interface, so this is quite expected.

I don't think this is Host AP driver, firmware, or hardware issue. It
sounds more like something setting interfaces down for some odd reason.
I can only come up with DHCP client as an example for now, but there
might be other programs doing it, too.
