Thread: Redirecting output to a file causes OOPS

  1. Redirecting output to a file causes OOPS

    When I redirect my output to a file on my NFS server, rather than to
    the screen, I get the OOPS below. I am running Linux 2.4.26. Any
    suggestions?

    Eclipse # cat /proc/dramFPGA/RxCOM > rxcom

    Machine check is supposed to happen when the processor discovers
    an internal error, such that the hardware isn't doing what it is
    supposed to do.

    It might be that on some processors it is possible to cause
    a machine check running code designed for a different processor
    model.
