Comment 14 for bug 1366351

Installed 3.17 on top of the 3.16.0-21
3.17 got a compiz failure too, see
https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1379073

Both 3.16.0-21 and 3.17 get compiz failures.

Note after the failure occurs, intrepid recovers and keeps on running.
Reboot and may run without getting the bug to repeat.

Install a new kernels and bug may occur again.
