(This is a message I posted to freebsd-questions@freebsd.org yesterday
with some additions)
Is there a (known?) problem with the lnc0 driver? I'm using a
NE2100 (the real thing, not a clone) and I get the following message
now and then;
Jul 2 11:22:45 key /kernel: lnc0: Transmit underflow error -- Resetting
I haven't noticed any other strangeness with the thing.
I also mailed hackers@freebsd.org about a problem with network card
a few days ago - this is the same setup except for the network card.
I recently tried to ftp a large (50M) file over to a Linux box on
the same ethernet with me, and these are the results;
Jul 3 04:31:55 key /kernel: lnc0: Transmit underflow error -- Resetting
Jul 3 04:31:57 key /kernel: lnc0: Transmit underflow error -- Resetting
Jul 3 04:32:41 key /kernel: lnc0: Transmit underflow error -- Resetting
Jul 3 04:45:32 key /kernel: lnc0: Transmit underflow error -- Resetting
Jul 3 04:46:12 key last message repeated 27 times
Throughput was something like 30k/s - I didn't try to ftp the whole
file over.
And this is what I got when I ftp'd stuff from the Linux box into
mine;
Jul 3 04:46:29 key /kernel: lnc0: Receive overflow error
Jul 3 04:46:31 key last message repeated 5 times
Does any else have this kind of problems with NE2100? I'd be most
delighted to know. I'll be trying a SMC Elite Ultra to see if it
works any better.
Other possibly relevant info;
