Comment 30 for bug 1041594

Testers, please try the new test kernel at:

For the record, we've determined that the problem was certainly caused by the addition of the Cypress Trackpad driver to the Ubuntu kernels -- so its definitely not a problem in any upstream kernel (as the Cypress driver isn't upstream yet). We think this latest test kernel should fix the problem (many many thanks to Seth Forshee, for diagnosing the apparent cause).
