        I’m not seeing an option to downgrade the kernel. Could you please share some documentation with me for that or tell me where I can do it?

            @ykarami You can get a different kernel straight from the WebGUI under Kernel Update. Just pick a 4.15 version. Make sure to get bit the x86 and x64 version to support all your clients.

              @quazz I keep getting this error message:

              Type: 8, File: /var/www/fog/lib/hooks/submenudata.hook.php, Line: 74, Message: Undefined index: node, Host: 192.168.9.100, Username: fog

              EDIT: Never mind, I got it to work

                  @ykarami Would you mind telling us what was wrong and how you solved the submenudata.hook.php, Line: 74, Message: Undefined index: node

                  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)

                  Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

                    @sebastian-roth Normally the messages correlate with user information being incorrect. The File it’s hanging on (the submenudata.hook.php, just happens to be a portion of where it failed, but most likely unrelated to the problem itself).

                    Of course, @ykarami please post what you did to solve the problem, it would help us and potentially other users as well.

                      I had the same issue with the slow Erasing current MBR/GPT table. I followed @Tom-Elliott advise of downgrading the kernel to 4.15.2 and now it is working without issues.

                        @fogmania @ykarami Good news to all of you, we have figured out what is causing the slowness and fixed it. It’s been a longer story [ref] - thanks again to @Quazz for doing lots of testing and finding very helpful stuff to figure this out!

                        As we have not had enough time to push for a new release yet you can simply update to the latest kernel and inits like this:

                        sudo -i
                        cd /var/www/fog/service/ipxe
                        mv bzImage bzImage.orig
                        wget https://fogproject.org/kernels/bzImage
                        mv bzImage32 bzImage32.orig
                        wget https://fogproject.org/kernels/bzImage32
                        mv init.xz init.xz.orig
                        wget https://fogproject.org/inits/init.xz
                        mv init_32.xz init_32.xz.orig
                        wget https://fogproject.org/inits/init_32.xz
                        

                        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)
