Usually there is more to the message than the above when a kernel
experiences a "panic". When this panic occurs again, try to capture as
much of the text from the console as possible (I often take a snapshot
with a digital camera, and jot down notes on paper). The more detail
you can provide the developers, the better.

And, if (when) you're brave enough:

Also, I think it may be appropriate at this point to test your
computer's RAM (using a "memtest"-type utility); doing large,
intensive tasks such as building OpenOffice is bound to uncover issues
with your computer's hardware -- I know this from experience :)
