Just tried a test kernel built with rev 1.81 of src/sys/dev/ic/i82557.c
and after about 30 minutes of intense testing could not generate a single
device timeout. Traffic levels per direction were kept around 2.5Mbps out
and over 40Mbps in on the interface that was "constantly" timing out
yesterday. This was considerably more than the levels present during the
So, unless there are other factors involved (and not present today),
then the fxp device timeouts were indeed caused by rev 1.82
I'll leave 1.81 running for now, and should there be any timeouts,
I'll report them here (current-users thread).
Thanks for the quick fix!
