XP/Mandrake 9.1 laptop dual boot system keyboard/mouse freeze on warm reboot
 

Hello again after a longish absence !
I would be most interested to hear if anyone else has had the same problem and if so what they did about it.
I have an Evesham Micros laptop with 1.5Mhz Centrino processor and the ah, very well known Intel i810 chipset. This machine is configured with a Win XP Professional/Mandrake 9.1 dual boot. Linux is my preferred OS but I am not able to ditch Windows due to the Open University which provides course materials in Windows only format.
I had no problem installing Mandy on this laptop save for the well known acpi problems which were overcome with help from Google and this board.
The problem I have is that if I have to use Windows for a period of time :( and then want to switch to Linux, I have to let the laptop cool down completely before I can get a usable system on reboot! If I attempt a warm reboot (eg. from Windows shutdown screen) Mandrake will eventually boot - after hanging seemingly for ever on 'finding module dependencies' - but I cannot use the system, because neither the keyboard nor the touchpad mouse work properly; Keyboard input, for instance, takes something like an entire minute for each character...
The same thing happens if I switch the laptop off altogether and wait - but not long enough. If there is any heat left in the machine at all, the same thing happens.
So: why does my Mandrake install work perfectly from cold, but refuse to respond (or so nearly so that the system is unusable) when the machine is even slightly warm? Any clues gratefully received.

Many thanks

Jane

PS I have tried local and www search engines and 'has this been asked' on this board, and found nothing relevant, unless I'm simply too ignorant to realise something is relevant, in which case apologies.
