[Buildroot] Problems with generating an x86 Image

Hi there,

i'm having problems with generating an x86 image for an industrial pc
based on an AMD Embedded G-Series APU which runs perfectly fine using

Here's what i did, using Buildroot 2020.02.10:

make pc_x86_64_bios_defconfig

make menuconfig changes:

Filesystem Image: 250M size

iso image

initial ram filesystem

Networking applications - wireless-regdb (to get rid of an regdb error
while booting)


dd disk.img to USB drive, and then copy bzImage to /boot on the USB drive.

Boot my target system with clonezilla to console, and then dd the usb
drive to /dev/sda

When i reboot and remove the usb drive, grub starts and selects
"buildroot" after 5 seconds, and then the boot starts but i don't get to
the console. It stops with:

Welcome to Buildroot

buildroot login: scsi 0:0:0:0: Direct-Access Generic Ultra HS-COMBO 1.98
PQ: 0 ANSI : 0

sd 0:0:0:0 [sda] Attached SCSI removable disk

random: fast init done

random: crng init done (coming up after some minutes)

And there it just stops, with a blinking cursor. Can anyone point me to
what i am doing wrong?

If not, is there an easy way to access and save the console output that
comes up before these last lines to get a better understanding of what
is happening?

Thanks a lot!
