Unless you use those HP utilities:

# journalctl -p crit

Nasty message but no slowdowns. But it's printed just during desktop session 
start so it's no problem. Still, I wonder what this utility tries to do 
(seems to put itself into autostart with an "-s" switch but without 
supporting it, probably a packaging and/or KDE issue). At least HP thinks: 
Oh boy - that's really critical! Whoohoo. Why not let the system explode? 
:~)
