**
kgoeser, thank you for taking the time to report this bug and trying to
help make Ubuntu better. However, the Mactel PPA is not a software
package provided by the official Ubuntu repositories. Because of this
the Ubuntu project can not support or fix your particular bug. Please
report this bug to
Miklos Juhasz: The script you provided does appear to fix the problem.
I verified that the problem still exists in today's version of Natty.
Then I installed the script and run the MacBook through about 5
sleep/wake cycles, and the problem does, indeed, seem to be fixed.
I guess the next step
Status changed to 'Confirmed' because the bug affects multiple users.

Luke Scharf: You can create a file /usr/lib/pm-utils/sleep.d/02touchpad
with the following content:
CUT HERE

if [ -e '/usr/lib/pm-utils/functions' ];then

fi
suspend_bcm5974() { /sbin/rmmod bcm5974; }
resume_bcm5974() { /sbin/modprobe bcm5974;

** Description changed:
After suspending to disk and resuming, the touchpad stops working (no
mouse movement no clicks). This worked before upgrading to natty. I
guess, it is a problem with the bcm5974 driver from the mactel support
ppa (package bcm5974-dkms).
AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.

For a workaround, is there a script that is called (or can be called)
when the laptop comes back from sleep?
I've just started poking around Natty's power management daemons, but
I'm wishing that I could just put a script containing the line rmmod
bcm5974 ; modprobe bcm5974 in something like
Problem confirmed on MacbookAir3,2 with Natty. It happens in 20% of the
resumes.

I can confirm, that removing and reloading the bcm5974 fixes the
problem. Maybe it should be blacklisted for power management?

MacBook
I see this on my MacbookAir3,1 on Ubuntu 11.04, sudo rmmod bcm5974;
sudo modprobe bcm5974 has always fixed it. Using bcm5974-dkms 1.1.9
from the mactel-support PPA on kernel 2.6.38-8.42.

Oh and I don't use hibernation, just suspend-to-ram, so hibernation is
not the trigger for this bug.
