I have searched which patch is the culprit.
I appears that the 2.6.17.3 kernel is OK and the 2.6.17.4 is showing the
problem..
diff --git a/kernel/sys.c b/kernel/sys.c

break;
}
I've checked and this is really the culprit.
Recompiling the 2.6.17.7 whith the patch reversed got the kernel on
track again.
I can't figure why this cause the problem.
Can you have an explanation for this ?
