I have a mac pro running amd64 -STABLE from about a week or so ago.

The console and dmesg output are flooded by 

  acpi_smbus_read_2: AE_ERROR 0x10

message.  There will be a couple, then silence, then a burst of them,
then....

The don't seem to be hurting anything, but they push other stuff out
of dmesg.

Can anyone help me identify the problem and reduce the chatter (short
of commenting out the line that's generating the output...).

Thanks,

g.
