    actually it's very serious, something is scribbling all over your
    memory, it's just a matter of time before that overwrites something
    important on your filesystem, and then you have a high risk of losing
    most of your data.

    However, since you're using 2 proprietary kernel modules, you really
    ought to contact the vendors for those modules for support; they're a
    very likely cause for problems
    (for example, these two are the cause for the number 1, 2, 5 and 7 of
    the top 10 kernel oopses/crashes for the last week)
