    Hi,
    please excuse my lame explanation, but i'm not a kernel hacker ... i'm only
    (stupid) user.
    When i played with ISDN dial-on-demand combined with mppp channel bundling
    kernel oopsed everytime i tried to reconnect the link with some packet.

    Here are some facts:

    ippp0 master, huptimeout 5 secs
    ippp1 slave, huptimeout 30 secs

    # ping ns.jhrnet.cz
    <the interface goes up>
    # isdnctrl addlink ippp0
    <slave too ...>
    # ping ns.jhrnet.cz
    PING ns.jhrnet.cz (194.228.118.194) from 195.70.157.129 : 56(84) bytes of data.
    64 bytes from 194.228.118.194: icmp_seq=0 ttl=248 time=238.4 ms
    ....
    ^C
    <wait until ippp0 hugs>
    # ping ns.jhrnet.cz
    <Kernel oops>

    Yes, i know that it's stupid to set huptimeout for slave larger than for
    master, but it's not good to get an oops anyway ...

    I hope it will help someone to find and fix this bug (i'm unable to find or
    fix it by myself).

    Sincerely,
                       Wejn
