Hello I am using a Tyan S4882 motherboard with 4 CPU's that has a LM85 sensor chip which reports the following message during boot: . . ipmi device interface Enabling SMBus multiplexing for Tyan S4882 lm85 0-002e: Client (0,0x2e) config is locked. lm85 0-002e: Client (0,0x2e) is not ready. lm85 0-002e: Client (0,0x2e) VxI mode is set. Please report this to the lm85 maintainer. Looking at /var/log/messages I also can see multiple entries of: i2c_adapter i2c-0: SMBus collision! OR i2c_adapter i2c-1: SMBus collision! OR i2c_adapter i2c-2: SMBus collision! OR i2c_adapter i2c-3: SMBus collision! OR i2c_adapter i2c-4: SMBus collision! This happens with lm_sensors 2.9.2 and 2.10.1 and plain kernel.org kernels 2.6.16.x to 2.6.19.1. Any idea what is causing this and what I can do to remove the problem? Thanks, Holger --
