Assertion failed on FPU

Hi all,
I'm trying to get L4Linux running on my raspberry pi(model B) but there is
something wrong that I couldn't figure out.
The error message is:
Assertion failed: 'Fpu::fpu.current().owner() == current()' [ret=0xf0013544]
/home/soap/project/L4/kernel/fiasco/src/kern/arm/thread-arm.cpp:800 at
f0012b7c
The value of "Fpu::fpu.current().owner()" is 0 which seems to be the value
set when fpu initialized.
Can anyone help me to fix it?
FPU is enabled in Fiasco config and the hello example works.
All the components are at latest revision(l4linux:41, fiasco:59, l4re:59)
Please let me know if something is missing.
Here's the full log:
