Howdy.

I have a new Linux box (running Redhat 5.1 + updates) with an Intel
EtherExpressPro 100.  Things have been running smoothly until I added
the NetAtalk package (v1.4b2) for Appletalk support.  A short time
later, I started seeing lots and lots of transmit timeout messages.
At the same time, my network connectivity started to suffer, both
outgoing and incoming.  Basically I lose network connectivity for
about 10 seconds at a time.

I've read the email archives and the symptoms match the multicast
problems that have been reported in the past.

Here  is what I've done:
  1) Upgraded to the latest driver (from 0.99B to 1.03).
  2) Added "options eepro100 multicast_filter_limit=3D0" to my
     /etc/conf.modules file.
  3) Tested with both Appletalk on and off (Kernel module).

Nothing has corrected the problem.  As long as Appletalk has not
loaded since boot-time, things are fine.  Once Appletalk is loaded,
the problem persists, even after Appletalk services are stopped
(though the kernel module remains active).

I'm including some sample log messages (both eepro and NetAtalk),
plus diagnostic outputs with information I'm trying to collect.  This
is all with Appletalk loaded and mostly active (except for the bug).

I'm stuck at this point.  I'd like to have both Appletalk and Samba
loaded for various services.  I'll be trying Samba momentarily,
after I shut off Appletalk... :)

Thanks for any assistance you can provide.
