    After upgrading from 5.2.1 to 5.3-RC1 (including a recompile of all
    ports), I noticed my system locking up when there was a high network
    load. A common way to reproduce this is to run a BiTTorrent client and,
    say, copy a file to another local machine over NFS. The computer does
    not respond to pings or any key presses. I'm using the lnc(4) driver
    for an AMD PCnet PCI ethernet card (exact model escapes me)
    [Am79C970/1/2/3/5/6 PCnet LANCE PCI Ethernet Controller]. (I'm aware of
    the pcn(4) driver, but cannot get it to recognize the card). I can
    reproduce this with both the 4BSD and ULE schedulers, if that matters.

    All relevant sysctl variables are defaults. Is this a known issue?
    Any ideas? Thanks.
