    Unhappy A screen full of messages and computer locks up


    My computer will be working normally when suddenly a screen full of messages (errors?) appear and the computer locks up. I have to force shutdown using the power button. This tends to happen between 20 minutes and an hour after the computer starts.

    I have Ubuntu 10.10 Server installed on the system, but I also have the same problem using Gentoo liveCD.

    Here are the messages I get when it does this:

    [<c08a401e>] ? sd_prep_fn+0x5f/0x7ff
    [< ... >] ? cfq_dispatch_insert+ ...
    [< ... >] blk_peek_request+ ...

    [< ... >] ? rest_init+ ...
    [< ... >] ? start_kernel+ ...
    [< ... >] ? i386_start_kernel+ ...

    I removed the numbers and letters at the beginning and end of each line after the first, but I can get them if needed.

    I am not really sure what this is or how to fix it. Any help will be much appreciated.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    Since this happens both with the installed Ubuntu server distribution, and a Gentoo LiveCD, then it is probably a hardware failure. You need to get and run diagnostics on the hardware (motherboard, RAM, NICs, etc).
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
