piix4 fails to reset? (ticket #1078)

>From a module compiled with debug information:

i2c-piix4.o: Transaction (pre): CNT=00, CMD=19, ADD=78, DAT0=25, DAT1=00
i2c-piix4.o: SMBus busy (01). Resetting... 
i2c-piix4.o: Failed! (01)

It seems like the i2c bus is stuck, or the piix4 is in a pooched state.
Why would this be, and what can I do about it?
