    SubjectCyrix and the 2.0.35-pre6
    From
    Date
    I've been using Cyrix for about a year now, and have always been having
    problem with lockups and 'instant reboots'. I stumbled across some info
    that the upcomming 2.0.36 should have better Cyrix detection and bug
    workaround, but so faar it doesn't work for me.

    This is what /proc/cpuinfo tells me:

    ----- s n i p -----
    processor : 0
    cpu : 486
    model : 486 DX-25/33
    vendor_id : GenuineIntel
    stepping : unknown
    fdiv_bug : no
    hlt_bug : no
    f00f_bug : no
    fpu : yes
    fpu_exception : yes
    cpuid : no
    wp : yes
    flags :
    bogomips : 119.60
    ----- s n i p -----

    And this is what 6x86_reg says:

    ----- s n i p -----
    6x86 (Classic/L/MX) Register Dump utility

    6x86 DIR0: 0x31 2X core/bus clock ratio

    Wait a moment...

    6x86 CCR0: 0x2 NC1 set (address region 640Kb-1Mb non-cacheable)
    CCR1: 0x92 NO_LOCK set

    RCR = 0x1 : not cached
    ARR2: disabled
    ARR3: address = 0xE0000 , size = 32 KB
    RCR = 0x9 : not cached, write gathering

    ARR7: address = 0x0 , size = 64 MB
    RCR = 0xB : cached, weak write ordering, write gathering

    Now, I got a lot of info on the 'http://gwyn.tux.org/~balsa/linux/cyrix/index.html'
    pages, and uses the 'rc.cyrix' at boot (the original one, since I didn't understand
    much about what it does etc).

    I still got the general protection, and a couple of minutes later, it freezes,
    and the watchdog reboots the machine.

    Sometimes, when I'm using X and Communicator, al of a sudden, I see the BIOS
    starting to count and check the memmory! That's a fast reboot for ya'... :)

    I'd surely would appreciate some assistence here, I'm getting a little to
    many gray hairs about this, to be funny...
