          @Jimbohello After you are able to image the machine, could you provide feedback on if the kernel args works for you or you had to go the debug route and enter the instructions directly into the console? We are trying to collect information on which solution works the best for resolving these issues with these specific nvme drives.

          In short these two commands (applied differently) keep the drive from going into low power mode during imaging. The developers are working towards a solution where the imaging engine will adapt these commands without intervention.

          Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

            After analysing the situation, here are my conclusion
            i did add your code : nothing change
            same slow ridiculous speed
            maybe your not looking at the right place for the bug ! of slowness
            we use FOG for more than 3 years, alway the same SSD and Same Machine, closely.
            so conclusion, has nothing to do with nvme_core.default_ps_max_latency_us=0
            nothing has change in our environnement except we upgrade fog every 1-2 mounth.

            thank’s

              @Jimbohello Something had to have changed. And if this were a bug in the code, chances are highly likely that we’d have a lot more posts regarding the issue (as it would impact everybody.)

              Something changed. I don’t understand why you update fog every 1-3 months. Last official release was 1.5.7 (July 2019). Are you running a dev-branch version? When you say you upgrade fog, do you mean the OS components (e.g. apt-get)?

              Have you looked at BIOS upgrades that may be happening? Pictures of the issue would be handy too. (Yes we want to see the blue partclone screen).

              I still think this is in your environment. I don’t know where or what, and the fact that things worked okay, then started getting slow, without knowing more this is very " you guys did this now you fix it " and we don’t know how to help.

              Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

              Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                @Jimbohello Have you tried the other suggestion yet??

                Schedule a task in debug mode and before you start the job run this command in the command shell on the host PC: nvme set-feature -f 0x0c -v=0 /dev/nvme0

                  @Sebastian-Roth He’ll need newer inits that include the NVME package since it wasn’t included in the 1.5.7 package iirc.

                    Agree with you !
                    i’ll get back to you very fast
                    but for now, i’ve created a samba share and i get full speed of what a gigabit nic can give so arround 112-120 mb/s
                    with acronis.

                    FOG 1.5.7.99

                      We did have reports of another user who had fast speeds with acronis as well. Turns out Acronis is using a fairly old kernel which doesn’t seem to have the issue. If you are keen to give an older kernel a try:
