I have to take some of what I said back. The network stalls were actually
due to a lot more stupid problem: the server went into a power saving
state and the NIC IRQ didn't wake it up (mouse did). After I disabled the
the relevant stupidnesses from the BIOS setup, it now works.
The error message, however, does appear with the 2.2.18pre17 eepro100.c,
while as the Becker's version does not show it for whatever reason.

I run 2.4.0-test10-pre5 and it still does it.
Trick : "ifconfig eth0 down" then "ifconfig eth0 up" stops the problem for me
when it occurs.

We were seeing this on a firewall a week or so ago -- it was actually
coming from some sort of arp flood/loop on the uplink not being caused by
us, and the speed of the incoming arp packets would cause these messages
to occur.
We tried ifconfig up/down, warm reboot, cold reboot, power cycle, card
swapping, and the messages continued. We stopped the card with a 3c905
and the messages stopped, but "ifconfig" showed Rx overruns at about the
same frequency as the messages used to occur. This is probably another
way to trigger this error than what most people are seeing.

I've not been paying attention to this eepro100 issue but
a coworker mentions that she saw a driver (or patch) posted
here back around 6 Sep 2000 by saw@saw.sw.com.sg with
Subject: "Re: eepro100 trouble" that might be of interest.
Also, here's a possibly useless personal note WRT the
eepro100 resource msgs, FWIW: I was recently using remote
KGDB to work on an unrelated problem on an MP Pentium
box with integrated eepro100. Whenever I'd leave one CPU
stopped in the kernel debugger for a very long time I'd
get those "no resource" messages from (I believe it was)
the Enet driver when I finally allowed that CPU to continue
running. I never noticed any other ill effects though
I wasn't looking too hard for them at the time. I don't
know what caused those resource messages but the version of
KGDB I was using was not clueful about MP issues - while
that one CPU was breakpointed the other CPU was likely
only held in check as a side-effect, probably by being
prevented from acquiring one of the IRQ-related spinlocks.
Of course, it would probably only be notable if some kind
of resource exhaustion did NOT result from such locking
misbehavior, but it seemed worth at least a mention...

It may be a legitimate case of "no resource" messages: the receive ring
is full because interrupts aren't served for a long time.
The problem is spurious "no resource" conditions, when there are plenty of
ready buffers.
Best regards
