2.3.99-pre3 and network hang

[andy barlak]

sure way to lock tulip card found.
Cards used are "acer ALN-310U",  using Digital 21140-AF, 2 years old.
using 100mhz, 
Hub: netgear DS104 100/10.

System that never locks up is 
Linux tosko 2.2.14 #1 Tue Jan 4 18:19:14 PST 2000 i586 unknown,
on a FIC-503+, with a AMD-K6-350.

System that locks up is
Linux boska 2.3.99-pre3 #15 Fri Mar 24 06:42:33 PST 2000 i586 unknown
on a FIC-503+, with a AMD-K6-400.

Can make the ethercard network lockup occur by starting an X application
on the 2.2.14 system and displaying it on the 2.3.99 system.
In this case the "mtr" utility (my traceroute) is the application that
takes the network down in a few seconds.  mtr some.remote.host  brings
up a window, displays info about some host out there on the dialup
link, and locks the network in from 2 to 60 seconds.


dmesg shows the following:

NETDEV WATCHDOG: eth0: transmit timed out
eth0: 21140 transmit timed out, status fc660000, SIA ffffff20 ffffffff
1c09fdc0 fffffec8, resetting...
eth0: transmit timed out, switching to 10baseT media.

large ftp transfers (70meg) work with no hangs either direction.

What information would be more useful?
