Hello,

********************************************************************
my hardware configuration is:

2 Alphaserver ES40 running kernel 2.4.2smp
   with 3com905b FastEthernet PCI 

The configuration is switched, 100 Full Duplex autonegotiation.
********************************************************************

I insert the 3c59x module with debug=7.

I start an ftp transfer from machine A to B:

	machine A			machine B	

	ftp B				ftpd answering

	get bigfile		

bigfile is 500 Megabytes, and transfer fine at 11 MegaBytes/s perfectly

Now I want to stress/test fullduplex:

	machine A			machine B
	
	ftp B				ftp A
	ftpd answers to B		ftpd answer to A
	get bigFile			get bigFile2

The first of the above machines launching the get freezes.	

I include a file with my logs, the output of the crashed machine after
reboot.
I also include the output of uname -a, lspci -vx, vortex --aaee.

Thanks for any help, If some information is missing there do not hesitate to
ask.

Sebastien Cabaniols
