Hi l4Hackers,

I want to run the l4linux given in l4re-snapshot-2014092821. So, I built the fiasco and the l4re. I created an iso image with grub2 and the modules given in example (entry l4linux) as test:

make grub2iso E=L4linux MODULES_LIST=$cwd/l4/conf/modules.list MODULE_SEARCH_PATH=$cwd/kernel/fiasco/mybuild
qemu-system-i386 -m 512M -cdrom l4linux.iso -serial file:$cwd/log

I enabled needed options such as the VPCI bus and followed the instructions given in mails approaching my problem (http://os.inf.tu-dresden.de/pipermail/l4-hackers/2013/005938.html and http://os.inf.tu-dresden.de/pipermail/l4-hackers/2011/004861.html ). I can launch Linux but the boot crashes.

I also tried with VBUS and modaddr 0x02000000 with the same result. So I put the logs in a file. I tried unsuccessfully to see my mistake.

In addition, are the last warnings a problem?

My configuration:

I run a Kubuntu in a Vm:
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
it’s a x86-32bit

I have: gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2
I wanted to compile for i386.

I give to you the log file, the module list, and the l4lx-gfx.cfg used in modules.

Thanks in advance for your help,

Nicolas
