Heh heh. Sorry about this, I believe I have further information on
another older problem. Bill, remember those ethernet lockups I was
having with the 'xl' driver all those months ago that we could never
track down?
Well, they happen with the 'dc' driver too. But this time I'm not getting
a complete lockup. The network actually continues to work well enough,
well, just barely well enough, that I can still use it. slowly.
It appears that the 'dc' driver continues to take receive interrupts
(see the systat -vm snapshot at the end), but winds up not processing
any of the packets. Except when 64 packets accumulate then suddenly all
64 get processed all at once! Then nothing again until the next 64
accumulate.
This netstat is on the machine with the 'dc' driver that locked up, when
I ping it from another machine. The 'dc' driver still works--- barely.
It doesn't processes any packets until 64 have been received, then it
processes them all at once. The transmit side appears to work fine and
the receive side appears to get interrupts but does not appear to process
incoming packets. Yet, obviously, the packets are being accumulated
somewhere because I don't have any packet loss, just incredibly long and
odd ping times.
This occurs when I am running netscape on the same box over a remote X
connection (read: Lots of packets going over the network plus lots of
local PCI activity talking to the graphics card). Same problem occurs
with different graphics adapters but I believe this same problem also
occured with the 'xl' driver on the card I had in before I put this
card in.

And watch what happens after I managed to 'ifconfig dc0 media auto',
it goes back to normal... suddenly everything is working properly
again.
