If I take the card out while it's suspended and put it in later after
the system is fully resumed, it just comes back as it should.
The laptop runs DHCP so it seems to spawn additional "pump" processes.
However, if I pop it out and back in while the system is up and
running, it will kill all the rest of the errant pump processes.

I was receiving messages when I suspended and resumed without
touching the card:

eth0: command 0x5800 did not complete! Status = 0xffff
eth0: command 0x2804 did not complete! Status = 0xffff
eth0: command 0x3002 did not complete! Status = 0xffff
eth0: command 0x3002 did not complete! Status = 0xffff
eth0: command 0x3002 did not complete! Status = 0xffff


I will enable debugging and let you know what I find.

Thanks,
Tom
