    Now that pastebin is working again:

    The 3.0 oops is fixed by this git commit:
    7676e345824f162191b1fe2058ad948a6cf91c20
    which was merged on July 28.
    Dave Miller wrote that he would submit it for -stable also.

    Um, same fix for the 2.6.39.3 oops.

    BTW, just putting the kernel oops logs inline in the email (or even as
    attachments) is usually preferable to making someone use a web browser
    to view them.
