Dear Matthias, 

You are right about the PCI. I checked the configuration and unfortunately the PCI support was not checked. I selected it and I have seen logs for e1000 and PCI support. However, unfortunately now I get kernel panics. This is shown in the following debug outputs at the last 2 lines:

The following is the outputs during bootup until fb-drv takes the console: (moreover I wanted to show also dmesg outputs after boot and "lspci" or "mdev -s" outputs after mounting the /proc and /sys", however I could not copy them from qemu or virtual box as I could not activate serial console, please kindly find the screenshots in the respective order for the dmesg outputs" and sorry for the high load of debug outputs...)

Have you tried the "-serial stdio" option? I cannot see anything PCI or e1000
related in the L4Linux log. Can you post the result of "grep PCI .config" and
"grep E1000 .config" from your L4Linux config?

Matthias.
