..I don't have really understand this sentence.. :thinking:
Observing the structure I've got this directory..  go to 
http://www.nabble.com/file/p12310202/.config .config  to control if I've set
wrong this options about RTC..

I upload the  http://www.nabble.com/file/p12310202/.config .config  so you
can take your conclusions about the correctness of my modifications..

Here is the link to the  http://www.nabble.com/file/p12310202/.config
.config  of L4Linux.

However, the vmlinuz was be created correctly.

The output when booting is:

API Version: (87) experimental
Sigma0 config ip:001048a8 sp:002c9760
Roottask config ip:00110000 sp:00000000
Starting kernel /DROPS/kernel/fiasco/build/fiasco at 0030082c

Comport 0x0001 is not accepted by the uart driver!

Welcome to Fisco (ia32)!
DD-L4(v2)/ia32 microkernel (C) 1998-2007 TU Dresden
Rev: rUNKNOWN compiled with gcc 4.1.0 for Intel Pentium [ ]
Performance-critical config option(s) detected:
   CONFIG_NDEBUG is off

Enabling special fully nested mode for PIC

Assertion failed: '0'
  in /DROPS/kernel/fiasco/src/abi/kip.cpp:126
  at f00175d1

Press any key to reboot.


So, are there problems in the configuration of L4? Where is the .config of
L4? I don't find where to set ON the CONFIG_NDEBUG option using make
menuconfig during the compiling/building..

Faithfully yours, Massimo.
