Dear fellow fedora users, I had found a way to run this machine(the one that froze a great many times). I used boot parameter acpi=off and it worked fine, except when I connected to internet. I connected with an external usb modem and it worked for a while till it froze.

I was listening to music using mplayer and I pressed page up to play the next song and the machine froze. Is there a way to get a traceback or a log that will determine the cause of the crash?
