issue while running l4linux on fiasco_x86_32

Hi,
just for completeness:
my mail was a bit overhasty. Raja obviously works on top of x86, where
the USB driver normally isn't used as NIC driver. Therefore, my analysis
was wrong. Nevertheless, I can see from the log output, that he/she
(sorry for my lack of knowledge) uses an older version of Genode.
Nowadays, the L4Linux run script uses the KDB serial driver, and all
logging outout, as well as the Linux kernel console gets printed to the
same serial line. That output would be helpful, to see what NIC driver
is used, or what gets wrong on behalf of the drivers. Alternatively a
look into the "kdb.log" file would help.

Init will throw an "Unavailable" exception to its children, when they
ask for a service, for which no route is existent. In that case the NIC
driver in L4Linux would exit its probing routine, and everything is fine.
But if there is a NIC driver, and init's configuration claims it
provides the service "NIC", then the thread in init, that serves the
parent interface for the L4Linux task, will block until the service
"NIC" becomes available, as soon as L4Linux tries to open that session.
The result is, what I've observed in issue 744. If you state a service
will be provided, but it doesn't get announced, your dependent clients
will block forever.
