Something may be needed, but probably not a wait for idle (which may
never succeed on an SMP system). Other things you could try:
* Keep track of the hardware state in the driver, so you don't
have to read the registers all the time.
* Read/write the registers via MM_INDEX/MM_DATA instead of
directly.
I'm curious if either of this helps.
