problem: rtl8139 V1.17 and Linux kernel 2.2.19

We're trying to use a Realtek Ethernet chip (built into the motherboard) on a Linux 2.2.19 system.  

We originally using rtl8139.c version 1.07, but after a few hours under heavy loads (WebStone with 500
connections) it would start to report errors of various sorts.  Today, we tried upgrading to version 1.17,
from the scyld web site.  We also obtained pci-scan.c and the required headers from this same page.  When we
load this driver pair, it loads successfully, but when we try to ping through the driver, in reports: 

eth0: Abnormal interrupt, status 00000020. 
eth0: Abnormal interrupt, status 00002020. 

Has anyone ever seen this??  Any idea why this would happen??  We rebooted the system, and it's not happening now...

soooo... if Nasdaq drops below $1, will it delist itself??

Hmmm, this could be either a link change indication (overloaded on the
RxUnderrun indication), or a RxUnderrun.  Which chip do you have, and
what is the detection message?  If it's a rtl8139c, the second status
indicates that the cable has changed length -- perhaps due to the link
returning.

Oh, that was it!!  My co-worker had switched cables to try to solve a perceived comm problem, and we get the
first message when we disconnect, and the second when we re-connect!!  We just confirmed it by connecting
and disconnecting the cable again... Great...

Thanks for your quick help!!

OK, this extra message is noted as a buglet.  The message level is
NETIF_MSG_DRV, when it is closer to NETIF_MSG_LINK.
