I tried to compile l4linux (kernel 2.6.24) under ubuntu 8.04 (The version of gcc compiler is 4.2.3) and it failed to boot under l4env with Fiasco microkernel. Here is my step to compile l4linux

1. make O=/usr/l4/build/linux x86-native_defconfig
2. enable Support for frame buffer devices and Framebuffer Console support
3. make O=/usr/l4/build/linux

and then edited the menu.lst title L4Linux-2.6 root (hd0,0) kernel /boot/grub/common/bootstrap -modaddr 0x02000000 module /boot/grub/common/fiasco -nokdb -serial_esc module /boot/grub/common/sigma0 module /boot/grub/common/roottask task modname "bmodfs" attached 4 modules module /boot/grub/common/names module /boot/grub/common/log module /boot/grub/common/dm_phys --isa=0x00800000 module /boot/grub/common/simple_ts -t 300 module /boot/grub/common/rtc module /boot/grub/common/l4io module /boot/grub/common/bmodfs module /boot/grub/common/linux.cfg module /boot/grub/common/libloader.s.so module /boot/grub/common/libld-l4.s.so module /boot/grub/common/vmlinuz module /boot/grub/common/loader --fprov=BMODFS linux.cfg

and linux.cfg modpath "(hd0,0)/boot/grub/common" task "vmlinuz" "earlyprint=yes mem=64M"

It's earlyprintk (add a 'k' at the end) and you should hopefully see more.

it shows the following messages when it boots.

My l4linux config file is also attached for your reference.

I have read the document 'l4/Fiasco/L4Linux kickstart' as a guide and tried many times to reconfigure the kernel, but i got the same result.

I'd like to know where 007371a6 is in the code. Can you do a objdump -ldCS vmlinux and post me the output around the line starting with 7371a6: ?
