      @bloodwar Please plug the USB key back into a running (Windows) machine and edit the file boot\grub2\grub.cfg and add ,mmap to line number 6, so it looks like this:

      set myimage=/boot/bzImage
      set mydbgimage=/boot/11_bzImage
      set myinit=/boot/init.xz
      set myloglevel=7
      set pager=1
      set debug=linux,mmap
      set timeout=-1
      insmod all_video
      ...
      

      Boot from that USB key again - now you need to skip through the pages as there are many messages on screen… Best if you can take a steady video of all this.

      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)

          @bloodwar Yeah, but there are the debug messages from the last picture you took somewhere in between. I’d like to see exactly that screen as picture. Things like real_mode_target ... and real_mode_mem ... should be on there.

          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)

              @bloodwar The video is pretty good, though it’s not with the mmap debug enabled.

                Alright tried booting it up again. Held the spacebar till any actually information showed up. Problem is it scrolls way to quickly to record anything. Are therre any log files i can create/capture to show what it’s doing?

                  @bloodwar Don’t think it’s easy to get that information dumped to a file. But shouldn’t be necessary on the other hand. You just need to be patient and page through the messages one by one. I know this may take a couple of minutes. On the other hand this is just a plain test to see if any other loader can properly do the UEFI “exit_boot_service” stuff that seems to hang when we chainload the kernel through iPXE. Right now I am lost with ideas but will look through the code again…

                    @bloodwar I have looked through the code up and down, forth and back… Just don’t know all about UEFI and have no idea why this goes wrong. I am pretty close to sending a message to the kernel mailinglist. But before that I’d like you to try other kernels first. Please use some older kernels just to see if those can boot on that device. I think the easiest way is to download old kernel binaries here and here, plugin the USB key you made and put the kernel binary on it as EFI/BOOT/BOOTX64.EFI (rename that file - GRUB EFI binary).

                    Now boot the Lenovo N24 off that USB key and see how far you get. If you see Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)) than you are past the issue. If it just sits there for 3 minutes then I’d expect it to be locked. Please try at least 10 kernel binaries of various versions from the links above.
