    Hi,

    I have built world and kernel from -STABLE as of today (Sept. 24th).
    All seems to work well, but after a certain time (maybe hours, don't
    know really), the internet connection breaks.

    For example, immediately after boot, everything is okay:

    Mozilla connects to whatever, like a charm,
    and telnet/ping do as expected:

    $ telnet 61.74.111.134 13
    Trying 61.74.111.134...
    telnet: connect to address 61.74.111.134: Connection refused
    telnet: Unable to connect to remote host

    $ ping 61.74.111.134
    PING 61.74.111.134 (61.74.111.134): 56 data bytes

    -------------------------------
    then, after a while, when I do the same:

    Mozilla gives a dialog with
    "connection was refused when attempting to contact foo.bar.com"

    $ telnet 61.74.111.134 13
    Trying 61.74.111.134...
    telnet: connect to address 61.74.111.134: No route to host
    telnet: Unable to connect to remote host

    $ ping 61.74.111.134
    PING 61.74.111.134 (61.74.111.134): 56 data bytes
    ping: sendto: No route to host

    ------------------------------

    When I reboot, all is okay again.

    Any ideas what has caused this in the new build?
    What should I do to investigate further?

    See dmesg and uname info below.

    Thanks,
    Rob.
