    That's about what I did, except that I saved the data to a nfs mounted disk.

    Probably not. I tried the drivers from http://www.scyld.com/network/ , and
    the problem disappeared (thanks to Jeff Garzik for the suggestion).
    I haven't tried 2.4.x again, but last time I did (2.4.6-pre6 or so), it
    didn't even finish importing my nfs shares on startup.

    In case you are interested, here is the output of the 2.2.18 drivers, when
    the card hangs:

    Jun 4 16:44:34 siechfried kernel: eth0: Transmit timeout using MII device,
    Tx status 0005.
    Jun 4 16:44:34 siechfried kernel: eth0: Restarting the EPIC chip, Rx

    Jun 4 16:44:44 siechfried kernel: eth0: Transmit timeout using MII device,
    Tx status 0005.
    etc...

    The driver from scyld.com did also issue such a warning, but only once and
    everythings seems to be back to normal afterwards:

    Jul 4 15:13:06 siechfried kernel: eth0: Tx hung, 25721 vs. 25713.
    Jul 4 15:13:06 siechfried kernel: eth0: Transmit timeout using MII device,
    Tx status 0003.
    Jul 4 15:13:06 siechfried kernel: eth0: Restarting the EPIC chip, Rx
    24507/24507 Tx 25713/25721.
    Jul 4 15:13:06 siechfried kernel: eth0: epic_restart() done, cmd status
    000a, ctl 0512 interrupt 240000.

    I hope this helps,
    Flo
