Bug? 2.4.24 module/networking Kernel driver/net/r8169.c freeze

[Mathias . Beilstein]

Dear Maintainer:

1. short: smb over tcp delays > 5 sec; flood ping to machine --> machine 
freeze

2. detailed 

Machine is an Intel-Triton II Chipset (Tulip TC48) with an Pentium 233 MMX
Distribution is Suse 8.0 with selfcompiled 2.4.24 kernel
Machine runs for weeks stable with an rtl8139c with the rtl8139too driver.
Now I upgraded to a RTL8169s (32bit) GigEth.
First I recognised reread delay using samba. Analysing using ethereal --> the
tulip does not anser for 4 or 5 seconds.
So I did some stress using flood ping and the machine crashed with no reaction
at all. No OOPS or so.
I would say it looks like dma-buffer, irq-handling?

Enviroment 2 machine (Linux) and a level-one Fastethernet switch in between.
Autonegotiation works (sure). Links are on switch and NIC 100Mbit full duplex.

Output from the second machine about the link:
 mii-diag 
Using the default interface 'eth0'.
Basic registers of MII PHY #1:  3100 786d 0101 8f25 01e1 45e1 0007 2801.
 The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
 Basic mode control register 0x3100: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
 Your link partner advertised 45e1: Flow-control 100baseTx-FD 100baseTx
10baseT-FD 10baseT, w/ 802.3X flow control.
   End of basic transceiver information.

Any Information needed ??? Please ask for that.

Thanx Mathias

Greetings from Berlin


Output was made with the rtl8139C back in place to have network connectivity.
With the 8169s the same IRQ9 is used.
