Hello again No, my problem is not ahc related. This single processor system doesn't have any scsi It's a : PPro200/64MbRAM/8.4QuantumIDE/IntelVS440FX/Pioneer12x(which is not detected after upgraded to -CURRENT)/Digital 21240 (de0)/S3 Virge What I have in common with Christian is that it hangs during high usage, as I mentioned in my first post (e.g. compiling something, buildworld). I performed a buildworld this night with yesterday's code (in a common console) and it worked ok. I ONLY noticed this when having high CPU usage (e.g. compiling mysql port) when in using X. I am not saying this is X related. Common point here seems to be a busy system Joao Quoting "Dave J.
