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
