lost /dev/ipmi0 after 7.3->8.2 upgrade

[mitiok]

I lost device file for ipmi after 7.3->8.2 upgrade.

Before upgrade from dmesg:

kernel: ipmi0: <IPMI System Interface> on smbus0
kernel: ipmi0: SSIF mode found at address 0x84 on smbus
kernel: ipmi0: IPMI device rev. 1, firmware rev. 2.81, version 1.5
kernel: ipmi0: Number of channels 0
kernel: ipmi0: Attached watchdog

Part of kernel config file:

device          smbus
device          ichsmb
device          ipmi

ipmi was used for monitoring serverboard Intel SE7210TP1-E

ipmitool sdr

After upgrade I don't see any mentions of ipmi device in dmesg. Device files don't exist. Monitoring command gives:

# ipmitool sdr
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
Get Device ID command failed
Unable to open SDR for reading

I still see ipmi via dmidecode:

IPMI Device Information
        Interface Type: SSIF (SMBus System Interface)
        Specification Version: 1.5
        I2C Slave Address: 0x42
        NV Storage Device Address: 1
        Base Address: 0x00 (SMBus)

and ipmi-locate shows this:

# ipmi-locate

I tried to remove devices from kernel config to load modules via kldload, but still without success.

Any help?

Maybe try driver config? The driver may need to be subject to a re-make, because the computer might be using version-specific code (relative to operating system or environment). If the driver is NOT the issue, then maybe before upgrading, it may just be the module needed to be removed first. Sorry I can't help any more.
