  1. Bug#423015: SMBus controller no longer recognised by Etch.

    Package: kernel
    Version: 2.6.18-4-686

    Issue : The SMBus controller is no longer recognised by Etch.

    A Debian 4.0 "Etch" have been installed on a Desktop PC (Motherboard
    Asus P4B533) which previously ran on Sarge.
    The mbmon hardware monitor program didn't suceeded to access to the
    sensors, despite the fact that it worked perfectly on Sarge :

    # mbmon -d
    No Hardware Monitor found!!
    InitMBInfo: Success

    The system was rebooted on a knoppix 3.8.1 live-CD (kernel 2.6.11), and
    here mbmon works :

    # mbmon -d
    Using SMBus access method[Intel8XX(ICH/ICH2/ICH3/ICH4/ICH5/ICH6)]!!
    Asus chip ASB100(Bach) found

    If I do lspci with the knoppix live CD I've got the lines :

    ....
    0000:00:1f.1 IDE interface: Intel Corp. 82801DB/DBL (ICH4/ICH4-L)
    UltraATA-100 IDE Controller (rev 01)
    0000:00:1f.3 SMBus: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M)
    SMBus Controller (rev 01)
    0000:01:00.0 VGA compatible controller: nVidia Corporation: Unknown
    device 00f1 (rev a2)
    ....

    We can see here the Intel SMBus controller.

    If I do lspci under Debian Etch don't have any SMBus line, and no other
    peripheral at address 00:1f.3 :

    # lspci -M -s 00:1f
    00:1f.0 ISA bridge: Intel Corporation 82801DB/DBL (ICH4/ICH4-L) LPC
    Interface Bridge (rev 01)
    00:1f.1 IDE interface: Intel Corporation 82801DB (ICH4) IDE Controller
    (rev 01)
    pcilib: Cannot open /sys/bus/pci/devices/0000:00:1f.2/config
    pcilib: Cannot open /sys/bus/pci/devices/0000:00:1f.3/config
    pcilib: Cannot open /sys/bus/pci/devices/0000:00:1f.4/config
    ....

    The fact that the Intel SMbus controller is undetected prevents
    monitoring programs like mbmon to access the temperature and voltage
    sensors of the motherboard.


    All the best

    That is quite possible, but is very likely due to changes in the upstream
    kernel and not because of problems in the Debian kernel. I have the same
    issue with my Toshiba Satellite A40 laptop.

    The reason that Knoppix works is quite likely that it uses a much older
    kernel (2.6.11 instead of 2.6.18).

    Please see the following upstream bug reports for reference:
    http://bugzilla.kernel.org/show_bug.cgi?id=6315
    http://bugzilla.kernel.org/show_bug.cgi?id=6395

    If, despite the explanations in these references, you would like to follow
    up on this issue, you will need to file a bug report in
    bugzilla.kernel.org as this is not a Debian issue.

    Cheers,
    FJP

  3. Bug#423015: SMBus controller no longer recognised by Etch.

    Hello Frans,

    Thanks for your fast answer.
    I will try other kernel versions with liveCD and eventually file a bug
    report to bugzilla.kernel.org.
    I'll keep you informed.
    Cheers

    Pierre
