           Summary: Powerbook G4 12'' touchpad freeze
           Product: Ubuntu
           Version: unspecified
          Platform: powerpc
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: linux
        AssignedTo: ben.collins at ubuntu.com
        ReportedBy: cadamia at gmail.com
         QAContact: kernel-bugs at lists.ubuntu.com


On a Powerbook G4 12'' 867MHz (first generation) the touchpad freezes when
copying large files (30MB+) from the CD/DVD reader (not a superdrive).

As soon as copying  starts mouse cursor movements become erratic, lagging and
clicking on the screen at random, until after a few seconds it freezes
completely. The problem is less severe when copying a series of small files (but
still noticeable), as it hardly lags and never gets to the point of freezing
completely

After the touchpad stops responding the only thing that seems to solve the
problem is to reboot the machine altogether. Restarting X doesn't work.

A USB attached mouse doesn't exhibit this problem, it seems to be completely
silent since I can't find any logged messages and it's easily reproducible.

Thanks.
