I was having the same problems with 4.0 and taking out the saver module kept my machine from crashing. As far as the linux emulation... The same box that i disabled the screen saver is also running the linux module. It's still running it and seems stable, however the linux code itself is not being used, it's just loaded (i don't have any linux apps to test). I suggest you check if your kernels are being compiled with INVARIANTS or something of the likes, kernels compiled with these options mixed with modules that don't can crash your machine afaik. -Alfred > > > Kent Vander Velden <graphix@iastate.edu> wrote: > > > > Hi.
