Issues with IPMI_SI Driver

[prasadae31]

Hi all,

I am currently running OpenSuSE 11.0 on a SUN X4150 server with a home compiled 2.6.28.3 kernel from kernel.org.

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/2.6.25.16-0.1-default/kernel/drivers/char/ipmi/ipmi_si.ko): 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:
#dmidecode
<snip>
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
<snip>

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 ?

[prasadae31]

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.
