Hi all!
I compiled l4linux and trying to start it in qemu under Linux (Mandriva
2008.0). But when starting, linux is trapped
my menu.lst is like this:
[------------------------------cut------------------------------]

where l4linux26.cfg is the following:

Serial output is the following:

-- General protection fault at f0035e9b in l4lx.main
when i press 'u' in kernel debugger, the following unassembly around
the faulting instruction appears:

So, the trap occurs when returning from an interrupt handler.
And also the address 0xf0035e9b is seems to be somewhere in
L4 kernel, not in linux itself.
What it can be and how can I resolve this?
Thanks in advance,
Valery.
