Public bug reported:

Binary package hint: linux-source-2.6.20

Since upgrading to 2.6.20-16, I've been unable to suspend my Macbook.
Suspending and resuming worked fine with 2.6.20-15.

When I try to suspend with 2.6.20-16, I get some disk activity, then the
screen and disk both shutdown. The only indication that the computer is
on is that the white LED at the front turns on when I close the lid. I
can't wake the computer up from this state, either by hitting keys or
pressing the power button.

I believe this is a failure in suspend, not in resuming. Under OS X and
2.6.20-15, the white LED pulses when the computer is in suspend mode.
That doesn't happen when suspending under 2.6.20-16.
