    Hi there!

    I got this oops today after an uptime of many days.
    On the machine runs a squid and the fs's are ext3.
    It also exports some directories over nfs and has some
    iptables rules.

    After this oops squid hung in the kernel and was unkillable.
    Also a reboot did not work. Had to manually reset the server.

    Regards,
    Martin
