The kernel is 2.4.22-26mdk with a lot of patches by Mandrake, like supermount, 
etc...

QEmus is the only program I've used that does what I explained before, so I 
think it's safer to look at QEmu than to reinstall the whole system from 
scratch and sources. BTW, I think I've seen on some mobos some Mandrake folks 
using the software without complains. So I guess that some daemon, server, 
etc... is colliding with QEmu. It seems that QEmu, on my system, goes into an 
endless loop. Or it could be some SDL problem, but I've played games that 
rely on SDL and never had any problems. Bochs seems to run correctly as well 
on my system, so did VMWare and many other emus.

I think that the problem is within QEmu.
