I was just speaking about these lines in the dmesg output:

unknown: <PNP0303> can't assign resources (port)
unknown: <PNP0c01> can't assign resources (memory)
unknown: <PNP0c02> can't assign resources (memory)
unknown: <PNP0700> can't assign resources (port)
unknown: <PNP0501> can't assign resources (port)
unknown: <PNP0501> can't assign resources (port)
unknown: <PNP0400> can't assign resources (port)

What is the simplest way to test it ?

I have tried rebooting the computer in loop today (something like 20 
times) and it appears that the freeze is really totally random, 
sometimes it happens, sometimes not and when it freezes the frozen time 
is also random.

Thanks for your help.
