    @Sebastian-Roth said in Lenovo 300e ipxe boots ok but ipxe.efi can't resolve the system:

    @mjaskowski Hmmm, that’s interesting. In the output you posted I counted “Text output” 17 times. Now when I look at the code you posted it also has 17 lines of “Text output”. What that means is that it gets as far as the last “Text output”. That’s really good news because on most systems we debugged this we only got as far as setup_efi_pci…

    Ok, please add another efi_printk after the exit_boot call and check - see code here: https://elixir.bootlin.com/linux/v4.19.48/source/arch/x86/boot/compressed/eboot.c#L841

    Best if you make it a different text, e.g. “After exit_boot” so we don’t have to count the outputs.

    So not even the ‘Exit boot 1’ prints

        efi_printk(sys_table, "Text output 17\n");
    
                hdr->pref_address = hdr->code32_start;
                hdr->code32_start = bzimage_addr;
        }
    
        status = exit_boot(boot_params, handle);
        if (status != EFI_SUCCESS) {
                efi_printk(sys_table, "exit_boot() failed!\n");
                goto fail;
        }
        efi_printk(sys_table, "Exit boot 1\n");
    
        memset((char *)gdt->address, 0x0, gdt->size);
        desc = (struct desc_struct *)gdt->address;
    
        /* The first GDT is a dummy. */
        desc++;
    
        if (IS_ENABLED(CONFIG_X86_64)) {
                /* __KERNEL32_CS */
                desc->limit0    = 0xffff;
                desc->base0     = 0x0000;
                desc->base1     = 0x0000;
                desc->type      = SEG_TYPE_CODE | SEG_TYPE_EXEC_READ;
                desc->s         = DESC_TYPE_CODE_DATA;
                desc->dpl       = 0;
                desc->p         = 1;
                desc->limit1    = 0xf;
                desc->avl       = 0;
                desc->l         = 0;
                desc->d         = SEG_OP_SIZE_32BIT;
                desc->g         = SEG_GRANULARITY_4KB;
                desc->base2     = 0x00;
    
                desc++;
        } else {
                /* Second entry is unused on 32-bit */
                desc++;
        }
        efi_printk(sys_table, "Exit boot 2\n");

      @mjaskowski Ok, seems like it actually hangs on the exit_boot call. Doing a bit of research on this I found that we have another Lenovo device that does the same thing: https://forums.fogproject.org/topic/11060/debugging-lenovo-ideapad-miix-310

      Doesn’t help much but let’s keep that in mind.

      Ok, now we need to step into the exit_boot function, starting in line 704. Add those print statements here as well to see which call is the last.

      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)

        The last print I get is Exit boot 3

            status = allocate_e820(boot_params, &e820ext, &e820ext_size);

            /* Might as well exit boot services now */
            status = efi_exit_boot_services(sys_table, handle, &map, &priv,

          @mjaskowski Ok, I think we are down to the bones of this. Now we have to take one step back and also enable iPXE debugging to see what happens when the kernel quickly returns control to the UEFI firmware before it takes over for the rest of the boot process.

          Please leave all the kernel source code as you have it right now as we might need to get back to that to implement a fix at some point.

          Take a look at what is needed to compile iPXE here: https://wiki.fogproject.org/wiki/index.php?title=IPXE#Compile

          Beside the prerequisites you only need the following commands:

          git clone git://git.ipxe.org/ipxe.git ipxe-efi
          cd ipxe-efi/src/config
          rm console.h general.h settings.h
          wget -O console.h "https://github.com/FOGProject/fogproject/raw/master/src/ipxe/src-efi/config/console.h"
          wget -O general.h "https://github.com/FOGProject/fogproject/raw/master/src/ipxe/src-efi/config/general.h"
          wget -O settings.h "https://github.com/FOGProject/fogproject/raw/master/src/ipxe/src-efi/config/settings.h"
          cd ..
          wget -O ipxescript "https://github.com/FOGProject/fogproject/raw/master/src/ipxe/src-efi/ipxescript"
          make bin-x86_64-efi/ipxe.efi EMBED=ipxescript DEBUG=efi_wrap
          

          Then install the new iPXE binary:

          sudo -i
          mv /tftpboot/ipxe.efi /tftpboot/ipxe.efi.orig
          cp path/to/ipxe-efi/src/bin-x86_64-efi/ipxe.efi /tftpboot/ipxe.efi
          

          Boot the machine and you should get some very funky colored output on screen (for example see here). Please take pictures of the output you get on the screen and post here. We need all the details you see!

          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)

                  @mjaskowski Reading about “ExitBootServices” and “INVALID_PARAMETER” I found a few resources saying something about memory map being wrong:

                  https://forum.osdev.org/viewtopic.php?f=1&t=32519
                  http://mail-index.netbsd.org/port-amd64/2019/09/06/msg003003.html
                  https://lists.freebsd.org/pipermail/freebsd-hackers/2015-January/046956.html
                  https://uefi.org/sites/default/files/resources/ACPI_6_3_May16.pdf (p. 117,

                  Either it’s people developing their own operating system code and running into issues with their coding or it’s people running known operating systems that fail on particular hardware (probably because of UEFI firmware problems).

                  I am not sure if this is an issue that can be solved in iPXE but I will talk to the developers to see if they can help.

                    Argh! Thanks for all your help on this. I’ll see about getting Lenovo developers to cooperate or return their products.

                        @mjaskowski Still not much of an answer. I posted to the iPXE mailing list now too. Should be soon in the archive: http://lists.ipxe.org/pipermail/ipxe-devel/2019-November/thread.html

                        Did you get any response from Lenovo yet?

                          @mjaskowski I just remembered this and wanted to hear if you had any reply from Lenovo on this? No answer from iPXE developers mailing list unfortunately.

                          Have we talked about trying to boot this device using the USB boot method? Maybe it’s a good workaround for you to get around this. Take a look at this forum topic and let us know if you need help with it.

                            @Sebastian-Roth Hi Sebastian, I don’t use Fog project, but i use IPXE, and encountered this very issue myself. This is on a machine with elitegroup bios, and it has 2 nics.

                            I noticed couple things:

                            1. If i open BIOS setup screen, change nothing, but “save changes and exit” i do not see this issue.
                            2. If i open BIOS setup screen, change nothing, but “save changes and reset”, i get exit_boot failed error.
                            3. If i remove the nic that’s on pci, so i only am left with the one on motherboard, I do not see this issue.

                            Something with the memory map & nic card & kernel is a problem.

                            I am using similar script to this:
                            https://ipxe.org/appnote/debian_live

                            on debian buster.

                            Just in case this extra info helps.

                              @tunatoksoz Hmmmm, thanks for joining the discussion here! Seems like you are making progress on this more than we have. 🙂

                              May I ask you if this is on Lenovo 300e as well? As you are saying yours has a build in NIC plus one on PCI I kind of doubt you have the same machine. Can you be more specific on what make and model you see the issue on?
