    Hi,
    first of all, thank you for creating this awesome tool.

    I've got a fresh Asus Notebook G501VW with an SM951 (NVMe) SSD.
    I just needed a short term backup, so I wanted to backup onto the same local SSD (mode device->image).
    My old cz version seemed to work fine and I was able to set /home/partimag to the data partition on the SSD.
    My goal: GPT partitions 1,2,3,4 -> GPT partition 5
    (The version was clonezilla-live-2.4.5-23-amd64)

    Afterwards I needed another backup, but decided to update my clonezilla. Then the problems started :P
    I downloaded the current clonezilla-live-2.4.7-8-amd64.
    Afterwards I tried clonezilla-live-2.4.7-31-amd64 &
    like said here https://sourceforge.net/p/clonezilla/discussion/Clonezilla_live/thread/97a7870a/ ,
    I tried the xenial version clonezilla-live-20160627-xenial-amd64 with same results: It didn't work.
    (btw:
    EFI mode on,
    Secure Boot off and
    BIOS just offers AHCI mode)

    These versions have this new screen with "every 3.0s: ocs-scan-disk"
    And it tells me:
    ======================
    excluding busy partition or disks
    /dev/nvme0n1
    ======================

    So I can't set it as a local target ...

    I read on some forums here, that it might be due to secure boot, but enabling/disabling didn't help ...
    (With EFI on only xenial worked)
    Then I restored to clonezilla-live-2.4.5-23-amd64 and I could use the nvme SSD again.

    I have also some screenshots/photos of this problem if needed.
    I didn't find anything regarding "busy partition" and there are only 3 nvme related threads ...
    How can I help to find this bug ?
    Should I follow this instruction ?
    http://drbl.org/faq/fine-print.php?path=./2_System/21_how_to_debug_clonezilla.faq#21_how_to_debug_clonezilla.faq

    Or I can try Clonezilla live 2.4.6-3 vs Clonezilla live 2.4.5-38
    That's where the ocs-scan-disk was introduced ...

    Best regards
    Conker

    update:
    Did find Clonezilla live 2.4.6-3 here on Sourceforge:
    Doesn't work: Finds the device, but can't even find the Serial#

    Found clonezilla-live-2.4.5-38-amd64 on free.nchc.org:
    Didn't expect that. It doesn't work, too. (No new ocs-scan-disk menu, but doesn't show the nvme partitions)

    I am a little confused about what you have mentioned here:
    These versions have this new screen with "every 3.0s: ocs-scan-disk"
    And it tells me:
    \======================
    excluding busy partition or disks
    /dev/nvme0n1
    \======================

    So I can't set it as a local target ...

    Did you mean you press Ctrl-C after the message "every 3.0s: ocs-scan-disk" shown on the screen, then it shows you:

    \======================
    excluding busy partition or disks
    /dev/nvme0n1
    \======================

    Or?

    BTW, on which device did you put Clonezilla live?

    Hmm, sort of.
    Clonezilla is on sda1 (external usb flash drive). I have no other storage devices besides these two connected.

    1. First there is this "ocs-scan-disk" "screen" or message with the output listed above.
      \======================
      excluding busy partition or disks
      /dev/nvme0n1
      \======================

    Below there is this yellow text "update periodically ..."
    (btw: /dev/sda is not listed there)

    1. Then I press CTRL+C . The screen/view changes to the selection of what to mount as /home/partimag
    2. I want to select /dev/nvme0n1p5, but it's not listed there. There are only some other sda partitions (sda2, sda6),

    Ok, update:
    The current testing releases (clonezilla-live-2.4.8-7-amd64 and 20160919-yakkety) work both as expected.
