    Issues with IPMI_SI Driver

    Hi all,

    I am currently running OpenSuSE 11.0 on a SUN X4150 server with a home compiled kernel from

    I am trying to load the ipmi_si driver to use the IPMI Interface, and I get the error message upon load:
    FATAL: Error inserting ipmi_si (/lib/modules/ No such device

    dmesg | grep ipmi :
    ipmi_si: Trying SMBIOS-specified kcs state machine at i/o address 0xca2, slave address 0x0, irq 0
    ipmi_si: Interface detection failed
    ipmi_si: Unable to find any System Interface(s)

    And the section in dmidecode includes the following:
    Handle 0x0040, DMI type 38, 18 bytes
    IPMI Device Information
    Interface Type: KCS (Keyboard Control Style)
    Specification Version: 2.0
    I2C Slave Address: 0x00
    NV Storage Device: Not Present
    Base Address: 0x0000000000000CA2 (I/O)
    Register Spacing: Successive Byte Boundaries

    This is completely frustrating and I have done almost everything and nothing gets me anywhere. I will be grateful for any help! Thanks in advance.

    Did you try Google and the kernel param pnpacpi=off ?

    Yes, I did try it.
    adding pnpacpi=off kernel param was fruitless.
    I have been frantically googling hoping that someone has faced this issue.

    Note that I am not using the patches from OpenIPMI but trying the stock drivers in the kernel.

    Is there any other options to be enabled in the kernel config? Or am I better off using the patches from OpenIPMI? (The issue I have with the latter is that they do not have patches beyond 2.6.26

    Hey I figured it out.
    My hardware was flaky. When I visited the server room, there were issues with the hardware. (Blinking lights!)

    Thanks a lot though.
