hi Philippe,

> What does the panic message say? (eip, esp, current Adeos domain?)
i copied only what i found relevant:
it loads rt memory manager

then:
Kernel panic: Attempted to kill init!

ADEOS STATE: current domain=Linux on CPU #0 [stackbase=00000000]
   RTAI [cpuid=0]: priority=200, status 0x8 pending_hi=0x0
  Linux [cpuid=0]: priority=100, status 0x0 pending_hi=0x0

and i did the same test for a kernel compiled with APIC and other without (i
did a different fresh build of rtai 3.0 for each one).
both configurations give the same result. then i run testsuite/user/latency/
script and i got this:
- --------
/usr/realtime2/bin/rtai-load: line 230:   280 Segmentation fault      $sudo $insmod $rtai_moddir/rtai_$mod$modext
/usr/realtime2/bin/rtai-load: line 230:   238 Segmentation fault      ( cd $target_dir; inslist=""; children_pids=""; function cleanup () 
{ 
    if test \! "x$children_pids" = x; then
        $sudo kill -SIGINT $children_pids 1>&/dev/null;
        children_pids="";
        sleep 1;
    fi;
    if test \! "x$inslist" = x; then
        for mod in $inslist;
        do
            test $verbose = 1 && echo "+ $rmmod $mod";
            $sudo $rmmod $mod;
        done;
        inslist="";
    fi
}; trap cleanup SIGINT; while test -n "$target_deps"; do
    mod=`echo $target_deps|cut -d+ -f1`; target_deps=`echo $target_deps|cut -s -d+ -f2-`; if `echo $loadlist | grep -vq "\\brtai_$mod\\b"`; then
        if test -r $rtai_moddir/rtai_$mod$modext; then
            test $verbose = 1 && echo "+ $insmod $rtai_moddir/rtai_$mod$modext"; $sudo $insmod $rtai_moddir/rtai_$mod$modext; if test $? = 0; then
                inslist="rtai_$mod $inslist"; case $mod in 
                    up | smp* | ksched | lxrt)
 ./run: line 1:   206 Segmentation fault      ${DESTDIR}/usr/realtime2/bin/rtai-load
- --------

more information:
i'm compiling kernel and rtai setting CC and GCC to gcc-2.95 in command line
(debian installs multiple gccs at once). i've compiled using 3 different
machines but all of them are using debian testing.

i also tryed to trace it using kdb but it isn't trivial as signal arrives
and back trace is empty. is there a particular function that i should use as
breakpoint?
