[tulip] rtl8139/smc tiger array

[Chip Rodden]

I have a set top box with the following config:

233MHz Media GXM cpu
an on board rtl8139
a SMC dual port tiger array in the lone pci slot
running either 2.2.13 or 2.2.18 patched

Here are the symptoms:

The 8139 can get throughput of about 35Mb/s using iperf.  I'm using
the driver that comes with the corresponding kernels above.  I tried
to get an updated one but the ftp site did not appear to be up.

The box crashes ( I mean dead, no messages, just a bunch of garbage
in /var/log/messages, by garbage I mean a bunch of ^@^@) when I send any 
kind of somewhat fast pings to it.  When using the tulip 89h driver , it 
accepts pings sent once every micro second. The box crashes with a flood 
ping.

When using tulip 92t the box crashes on sending one packet every 1000us.

One other interesting note:  If the 8139 is not configured and
it's module not inserted a "ifconfig eth0 192.168.1.12" crashes
the box same as above.

Can anyone provide any meaningful insight and a possible reason,
or better, a solution to this?

Thanks
