ok, after few days of silence I am back with more questions
this time system feels little better, it is able to sustain for more
time that what 7.3-RELEASE could

I am using KDE4, and when OS freezes, well it freezes, means I cannot
change to tty0 and see the panic text, if any it might possibly have
spit. the stuck frozen GUI keeps staring there. So the question is how
to I capture that panic text ? unfortunately I am not getting core
files too, so there is nothing I can pick up hints
is there some option (KDB, DDB), so that on panic system drop to debugger ?
