I've come across a very strange behaviour. I wantet to try the live CD (Fedora-12-i686-Live-KDE.iso). It boots just fine, then works for a few minutes (not really enough to try anything out) and then just freezes. No reaction on any mouse click or keyboard stroke, not even Ctrl+Alt+F1 (for text console), Crtl+Alt+Backspace (to kill the X server) or Crtl+Alt+Del (for init 6).
Maybe it makes you feel better to know that the very same thing happens with the ubuntu live CD. So I guess this is not specific to Fedora but to some piece of the newer linux versions in general that doesn't work on my system. I'm running Suse 10.3 (about two years old) just fine but wanted to try other distros instead of just updating.
So - what info is needed to find the problem? I can't provide any log files since the system is just dead after such a short time. Does lspci help?
