Hi,

I removed all ore stubs from kernel, and no more ore related errors appear.
I think you misunderstood me Bjoern, I never said the system hang or crashed... It just doesn't display no more messages after that log, and L4-linux doesn't show-up on dope. If I understand how L4-linux works, after loading the ramdisk to memory, control should be passed to the kernel and some call yould be made to /sbin/init on the ramdisk to start the boot process.
I'm using the DROPS ramdisk on the L4_linux page @ (http://os.inf.tu-dresden.de/L4/LinuxOnL4/download.shtml#ramdisk) with this config:

task "l4linux2.6.21" "mem=64M load_ramdisk=1 ramdisk_size=16384 root=/dev/ram l4env_rd=drops-rd.rd earlyprintk=yes video=l4fb:800x600@16, xpos:214, ypos:140, refreshsleep:75, title:LegacyLinux"
 all_sects_writable
 allow_vga

I'm supposed to modify this "drops-rd.rd" to make the l4-linux boot work? I need to modify something to see a dope window where L4-linux will output? I'm puzzled because there is so little starting info...
Also, I've noticed this warning on the output: "*loader  | l4linux2.6.21,#e: Not allowed to perform any I/O". It appears if I don't use "allow_cli" on the above config file, is this relevant?
Thanks for your help and time.

Tiago Lopes
