Hi,all
I have compiled l4linux and tried to boot it in qemu environment. My hardware environment is CPU: Celeron D 2.53G，512M memor. Next is my menu.lst
title L4Linux kernel /bootstrap -serial -modaddr 0x2000000 module /fiasco -serial_esc -comport 1 module /sigma0 module /roottask task modname "bmodfs" attached 5 modules module /names module /l4io module /events module /dm_phys module /simple_ts module /rtc module /con --vbemode 0x117 module /bmodfs module /vmlinuz module /l4linux.cfg module /libloader.s.so module /libld-l4.s.so module /drops-rd.rd module /loader --fprov=BMODFS l4linux.cfg
In l4linux.cfg, I wrote
sleep 1 task "vmlinuz" "mem=64M load_ramdisk=1 ramdisk_size=16384 root=/dev/ram l4env_rd=drops-rd.rd" all_sects_writable allow_cli allow_vga
and I use qemu -serial stdio -m 200 -cdrom image.iso to boot, at fisrt it told me qemu didn't have enough main memory, so I assigned 200M, then I got the errors below

At last lines you will see the problem, and I checked the fiasco, it was ok. I found someone had similar problems but not the same, and Adam said L4Linux is not allowed to do port accesses (except it is explicitely allowed). I don't know what my problem is and I hope someone will give me some advice and thanks a lot.
