Hi Adam/l4-hackers,

 I tried to build l4+l4Re+l4linux for raspberry pi 2.
The build was successful, but when I tried to run this in qemu I am getting
the following error.
Could you pls help me to fix this error?
I am new to L4 and L4Re and would like to try out some virtualization
options with L4 Microkernel.
Could you pls suggest some initial modules or portions where I can start
with.

Regards
vmc
