[eepro100] Home made 82559ER NIC crash or hang linux 2.2.5-15

[Jiahua Wang]

I have a home made 82559ER pci card which has two
82559ER's and another pci device, total three pci
devices behind an intel/dec 21152 pci bridge. All
pci diagnostic tool tell me the card is fine.

When I repeat following commands several times
>ifconfig eth1 down
>ifconfig eth1 hw ether 00:aa:bb:cc:dd:ee:ff
>ifconfig eth1 up
it will crash the system

When I ftp a large ( ~100k ) file, it will hang
the system.

Any idea?

Thanks,

Jiahua
