Well, we don't have either of the above two scenarios.

We get "card reports no resources" all the time, with the frequency
apparently related to load (or rather, we see them more frequently during
our peak times).  We do not see anything like "can't fill rx buffer" in
the log.  The only kernel message being logged repeatedly is "card reports
no resources".
