How > do you troubleshoot something like this? The first thing to determine is that whether it is freezing of the user interface or the underlying kernel. For desktops I often compile the kernel with the option that it flashes the keyboard LEDs when it is panicking, so I can see at a glance that the omelette has hit the fan. So: a) This freezing behaviour, does it manifest only in X, or does it happen if you boot into a non-graphical environment? b) If both, is it possible to have your laptop on a private network with ssh/telnet listening? If so, please see if after the freezing behaviour, you can still telnet/ssh into the laptop? If you can, can you run top from the terminal and see if anything is just taking up 100% resource? Other things to check: c) could your laptop be overheating? d) is this a new phenomenon or something that has happened consistently since the dawn of time? i.e. did you update any software recently or is this something that just happened right out of the box with your spanking new hardware? e) If this is a spanking new machine, and if it comes with one of the bastard OSes pre-installed, does this also happen running that operating system?
