Hi,

after upgrading the BIOS to revision A06, the kernel cannot find the IPMI
device any more:

prompt# modprobe ipmi_si
FATAL: Error inserting ipmi_si (/lib/modules/2.6.15-26-amd64-server/kernel/drivers/char/ipmi/ipmi_si.ko): No such device

I use the following parameters for the ipmi device:

options ipmi_si type="kcs" ports="0xca8" regspacings="4"

which work perfectly for BIOS revision A04

dmesg tells me:

[1831781.675142] IPMI System Interface driver.
[1831781.675151] ipmi_si: Trying "kcs" at I/O port 0xca8
[1831781.675157]  Could not set up I/O space
[1831781.687878] Trying to free nonexistent resource <00000ca8-00000cac>
[1831781.687902] ipmi_si: Unable to find any System Interface(s)

dmidecode says:

IPMI Device Information
        Interface Type: KCS (Keyboard Control Style)
        Specification Version: 1.5
        I2C Slave Address: 0x10
        NV Storage Device: Not Present
        Base Address: 0x0000000000000CA8 (I/O)
        Register Spacing: 32-bit Boundaries

so the base address should be OK

Thanks in advance for any help.

Best regards,

Bram.
