Comment 34 for bug 1041594

Testers, I've updated the fix kernel to the 3.5.0-14.15 baseline. Please install this new version (amd64 and i386 builds are available). No change in touchpad functionality is expected, but you'll need this one to keep the fix installed once the stock 14.15 kernel gets released:

The fix has been committed to Ubuntu Quantal, and will appear in the next stock Quantal kernel after 14.15 (likely 3.5.0-15.16).

The fix has also been committed to Ubuntu Precise, and will appear in the forthcoming Precise kernel version 3.2.0-31.50.

Thanks testers, for all your help identifying the problem and validating the fix.
