    Hello.

    My kernel panicked at /net/core/skbuff.c (line: 93 "BUG();")
    That was the first time when I booted into it.

    The second time, it was fine till about 2 hours, while I was writing *this* mail. Rebooted all of
    a sudden (no idea as to where the problem was. It was _quick_. No messages, nothing).

    This is my first post. Please do correct me if I've supplied incomplete information. (the output
    of dmesg follows)

    regards,
    jaju
