I admin an alpha with
de0 at pci0 dev 5 function 0
de0: interrupting at eb164 irq 2
de0: DEC DE500-AA 21140A [10-100Mb/s] pass 2.0
de0: address 00:00:f8:06:29:15
de0: enabling 100baseTX port
and every boot, as soon as any significant network traffic occurs, it
gets such messages, first 96|256, then 128|512, then 160|1024, then
store-and-forward (at which point, of course, it stops). I have seen
nothing else unusual with de0, so I doubt it has much to do with your
"odd output errors".
