    Question Kernel Failure message: what does it mean?


    Hello. I recently upgraded my kernel to 3.2 from Squeeze Backports and since then I've been getting some kernel failure messages. That scared me quite a bit, but somehow everything still seemed to work. So, I wonder, what exactly is going on?

    Can someone please help me decipher this message and tell me whether or not I need to do something about it? I can tell it's related to the network card (which is clearly still working, otherwise I wouldn't be able to post here), but I'm afraid that's all I've been able to make out. I hope someone here will be able to shed some light on it.

    Here's the report:

    A search shows a number of similar 3.2.x kernel failure messages. Looks like there are still a few kinks to resolve. Might be worth checking which 3.2.20-1~bpo60+1 kernel is installed... there are three of them for i386 in the backports repo.

    If the stock 2.6.32-5 kernel is still installed I'd suggest keeping it, just in case.

    Thanks. Yes, I still have it, and will use it if it comes to that, but if possible I'd rather not because the old one doesn't have a good driver for my Intel graphics card and randomly makes my screen resolution default to 800x600. >.>

    I mentioned the three backports kernels because the problem might be there. One is for older, single processors, another for newer, multiple processors and the third has a real-time patch.

    Might be worth checking to make sure the kernel you installed is appropriate for your hardware.

    For the graphics, I'm not up on Intel driver issues but others here are, and could give you a hand with it. Posting the terminal output below would help others help you with suggestions.

    Code:
     lspci -v

    I installed the one for multiple processors because I have an Intel i3, and also because my 2.6 kernel was for multiple processors too. I don't think that's the problem.

    Here's the output of lspci -v.
