Public bug reported:

Hi there,

I recently upgraded my mid-2011 Mac Mini (aka Macmini5,1) from to Ubuntu
13.04 Raring from 12.10. Since then I've been experiencing frequent
freezes on my bluetooth keyboard and trackpad. By freezes I mean this:

If I'm typing, keys will occasssssssssssssionally stick or briefly not
respond. My trackpad is the same, except that the touch/click inputs
will be stuck on, meaning that single-finger clicks will be interpreted
as two-finger (right) clicks and the trackpad will not move. I can only
recccccccccccccccover from this situation by wildly tapping and clicking
the trackpad.

The freezes happen at random intervals, so I don't think it's a result
of any kind of regular timeout. But frequently enough that on average
they happen every few minutes. They don't last long (the above were
genuine examples of briefly stuck keys) so my suspicion is that it's
some kind of temporary bluetooth dropout/reconnection. I don't see any
lights flashing on my keyboard or trackpad, which usually happens in the
event of a full disconnection.

The only relevant log messages I can see are a bunch of these in syslog and kern.log:
kernel: [487681.166937] power_supply hid-90:84:0d:fd:c9:e5-battery: driver failed to report `capacity' property: -5

Which I suspect is a red herring. It's definitely not a hardware issue,
as this wasn't happening with the exact same hardware setup prior to my
13.04 upgrade. The machine has since been moved from my office to my
house, so I don't think there's any environmental/wireless interference
factors at play. I've replaced the batteries as well.

Let me know if there's any other information I can give that might help
you track down this bug. It is super irritating so I am very motivated
to help. I can probably get accccccccccccccess to a usb bluetooth dongle
if that would be useful in isolating whether it's a problem specific to
the Mac Mini's bluetooth controller.
