acpi_smbus_read_2: AE_ERROR 0x10 on a Mac Pro running -STABLE

[George Hartzell]

Hi,

I have an 8-way Mac Pro running -STABLE csup'ed a few weeks ago.  It's
generally working great, but

   acpi_smbus_read_2: AE_ERROR 0x10

pops up on the console several times per minute.  It doesn't seem to
hurt anything, but it fills up the dmesg buffer and just doesn't seem
right.

Does it ring any bells?  What add'l info can I provide that might help
shut it up?

Thanks,

g.
