I try to run L4Linux-2.6.17 on Fiasco, on native PC, and I have problems.
As I got the following error :
l4lx         | Filling lower ptabs
l4lx         | Done (1643 entries)
l4lx         | l4lx_thread_create: Created thread 0e.05 (timer.i0)

l4lx         |  unhandled page fault

after looking at the mailing list, it seems the "Use ldso for loading" option has to be configured for L4Linux.
I did so, but now, the load stops with the following messages :

loader | vmlinuz26 : Starting application using libld-l4.s.so
loader | vmlinuz26,#e : Loading binary
loader | vmlinuz26,#e : Loading ldso
loader | vmlinuz26,#e : Starting libld-l4.s.so at 00013870 via 0000bf60
then messages from io about PCI configuration, and go to jdb with message :
(e.00) jdb:
    --__main() returned

My grub.conf file is as following :

title L4_Linux 2.6
 root (hd0,0)
 kernel /l4_linux/bootstrap
 modaddr 0x06000000

and my linux26.cfg file :

modpath "(hd0,0)/l4_linux"
task "vmlinuz26" "earlyprintk=yes mem=64M root=/dev/hda3" all_sects_writable

Any help would be great !!!
