    I am getting logs like this with a Planet PCMCIA Ethernetcard ENW-3502
    (10Mbps) on a Highscreen laptop. I already reported this behavior some
    time ago on this list. Currently I use kernel 2.2.13pre9 (gcc version
    2.7.2.3.f.1). The number of logs increases by high usage of the card
    that is by doing things like ping -f. I can also exclude IRQ-problems.

    My ethenet adaptor stays alive, however there is some tremendous slowdown
    in data transfer.

    I agree ;-)
