Hard lock ups............

[ariestao@skymesh.com.au]

With the linux-image-2.6.38-2-686 kernel I get hard lockups without any 
obvious reason and working with different programs on my Acer Aspire 
3614WLCi laptop.

Not a real worry as I have kept the: linux-image-2.6.32-5-686 kernel 
and boot into that.

However, I was wondering what files I might check that could give me a 
clue to why this lappy behaves like this with that particular kernel in 
Squeeze fully updated?

Thanks for any replies if you have time to do so.
