On my PowerMac G5, I consistently get this error after a cold boot:

iichb0: I2C error

After a minute or so, the fans ramp up to maximum.

The error also consistently goes away after a warm reboot.  Nothing more 
in dmesg:

FreeBSD powermacg5.acadix  bacon ~ 211: dmesg|grep iichb0
iichb0: <Keywest I2C controller> mem 0xf8001000-0xf8001fff irq 42 on unin0
iicbus0: <OFW I2C bus> on iichb0
iichb0: I2C error
iichb0: <Keywest I2C controller> mem 0xf8001000-0xf8001fff irq 42 on unin0
iicbus0: <OFW I2C bus> on iichb0

No more runaway fans.

Does this provide any clues about the cause?
