[3com905b freeze Alpha SMP 2.4.2] FullDuplex issue ?

["Cabaniols, Sebastien" <Sebastien.Cabaniols@xxxxxxxxxx>]

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.
