Bug Description

When kernels are installed, or when update-initramfs -u is run on a kernel, it causes gnome-shell to freeze for a few seconds if the machine is booted with that kernel or a newly installed kernel. During the freezes, the mouse pointer is still movable but the rest of the screen freezes. Any clicks get ignored and keyboard input is buffered then executed once the freeze is over. Please fix this as it is a big time productivity kller. THis is happening on my zenbook pro with nvidia graphics.

It happens with mainline kernl builds and stock ubuntu kernels regrdless of stable branches that those kernels come from.
