    mounting none on /dev failed: No such device

    Hi

    I'm running Lucid with the 2.6.32-28-generic and 2.6.31-11-rt(abogani's ppa) kernels, on a fairly new laptop.

    When I boot the rt-kernel, right after grub I get a message:

    Code:
    mount: mounting none on /dev failed: no such device
    W: devtmpfs not available, falling back to tmpfs for /dev
    Then after a few seconds, I see a lot of fast moving text and then Ubuntu starts just fine.

    when booting the generic kernel, I don't see any text at all, but it uses just as long time as the rt-kernel, so I guess the problem affects both.

    Any ideas what this is about?

    Thanks

    Hey, sorry for my late answer.

    # /etc/fstab: static file system information.
    #
    # Use 'blkid -o value -s UUID' to print the universally unique identifier
    # for a device; this may be used with UUID= as a more robust way to name
    # devices that works even if disks are added and removed. See fstab(5).
    #
    # <file system> <mount point> <type> <options> <dump> <pass>
    proc /proc proc nodev,noexec,nosuid 0 0
    # / was on /dev/sda5 during installation
    UUID=65725cf4-1171-475d-909a-563c93c229ab / ext4 errors=remount-ro 0 1
    # swap was on /dev/sda6 during installation
    UUID=704f6f2b-d003-421c-bce2-11c54f11e675 none swap sw 0 0
    Thanks

    Thank you! Strangely I didn't find that thread when searching the forum before posting this one...
