    Hi,

    One machine regularly crashes.

    Linux version 2.2.16-3 (root@porky.devel.redhat.com) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 Mon Jun 19 19:11:44 EDT 2000
    processor : 0
    vendor_id : GenuineIntel
    cpu family : 6
    model : 7
    model name : Pentium III (Katmai)
    stepping : 3
    cpu MHz : 551.255
    cache size : 512 KB
    fdiv_bug : no
    hlt_bug : no
    sep_bug : no
    f00f_bug : no
    coma_bug : no
    fpu : yes
    fpu_exception : yes
    cpuid level : 2
    wp : yes
    flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr xmm
    bogomips : 1101.00

    Another one, I don't really know, but I was comparing /proc/cpuinfo on
    these two machines as they are supposed to have the same CPU:

    /home/wolff> cat /proc/version /proc/cpuinfo
    Linux version 2.4.3 (wolff@cave) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #52 Fri Apr 6 14:43:38 MEST 2001
    processor : 0
    vendor_id : GenuineIntel
    cpu family : 6
    model : 7
    model name : Pentium III (Katmai)
    stepping : 3
    cpu MHz : 551.263
    cache size : 512 KB
    fdiv_bug : no
    hlt_bug : no
    f00f_bug : no
    coma_bug : no
    fpu : yes
    fpu_exception : yes
    cpuid level : 3
    wp : yes
    flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse
    bogomips : 1101.00

    /home/wolff>

    Everything is exactly the same, except for the "cpuid level". Once the
    cpu family and model are the same, I'd expect the cpuid level to be
    the same too. In this case even the stepping is the same, so how can
    the cpuid level differ?

    Maybe this is a reporting difference between 2.4.3 and 2.2.16????

    Anybody care to shed some light on this?

                                    Roger.
