Hi list, (please CC me, as I'm not subscribed)

I was trying to run l4linux supposed to boot from a NFS root file system. I enabled PCI support and the virtual PCI bus. I was successfully able to establish a network connection to my NFS server, however shortly after I get:

l4linux | Page fault (non-resolved): pfa=6 pc=61fff9 Die message: Trap: 14 Trap: 14: 0006 [#1] ... Kernel panic - not syncing: Fatal exception in interrupt

I am mostly running a setup with the supplied example configurations. This is my setup:

* l4re: http://svn.tudos.org/repos/oc/tudos r33 * l4linux: http://svn.tudos.org/repos/oc/l4linux/trunk, r19 * run time environment: Debian Squeeze x86, gcc version 4.4.5, qemu (0.12.5) * I'm starting l4re with: "qemu -m 768 -vnc :1 -cdrom images/l4linux-mag-x86.iso -serial stdio -net nic,model=e1000 -net user" where l4linux-mag-x86.iso was generated by: * "make grub2iso E=L4Linux-mag-x86 MODULES_LIST=~/ssl/modules.list MODULE_SEARCH_PATH=~/kernel-build/:~/l4linux/:~/bootstrap/"

Moreover (hopefully) I attached all configuration files below. all remaining files are untouched from the example configurations.

This is the full output:

arno@l4:~/l4re-build$ qemu -m 768 -vnc :1 -cdrom images/l4linux-mag-x86.iso -serial stdio -net nic,model=e1000 -net user
