O2Micro insertion / removal undetected

[Jerry Lundy]

Greetings.

You are correct: the wireless card does not work. I can query it and set 
its parameters, but it fails to function otherwise. When I ping a wired 
host, I see repeated arp requests from the wireless client. The wireless 
client appears to be blind to the arp responses.

Additionally, while attempting to ping from the wireless host, it shows 
a series of kernel level syslog messages:

an0: device timeout
an0: device timeout
an0: discard frame w/o leading ethernet header (len 12 pkt len 12)
an0: discard frame w/o leading ethernet header (len 12 pkt len 12)

I've seen mention of interrupt routing problems before. Is this related 
to the "APIC PCI interrupt routing support" that is on the Must Resolve 
list for 5.2-RELEASE?

Are there any workarounds?

Thanks,

Jerry Lundy
