the problem huang described has nothing to do with linux at all! At least, 
there isn't a linux module entry in his/her grub configuration. I'm not sure 
why roottask got an invalid KIP mapping here, but would suggest to update the 
whole l4 source tree and fiasco kernel.

Nevertheless, this has nothing to do with your (sunshine007's) problem. As 
Adam has already told you, you probably have misconfigured your l4linux. You 
need to include (_not_ as a module) your disk-controller and the filesystem 
of your root partition whether it is a ramdisk, a harddisk or usb-whatever. 
However, this is not a L4Linux specific thing, you will run into the same 
problems when using native linux.

There is a lot of helpful information on how to boot a linux kernel without an 
initial ramdisk on many linux related sites. Potentially it would be easier 
for you to configure a native linux and boot it, without the whole fiasco and 
l4env stuff. When your native linux boots without usind an 'initrd', then you 
can transcribe your linux configuration to l4linux and try it again.
