** Description changed:
A while after logging on, the system gets really slow. Menus and window
movements take a while to respond, switching windows is slow, etc.
This is a regression, it was not like this using Ubuntu 12.10, it just
started on 13.04. Tried different desktops (Unity, GnomeFaillback,
Lxde). They all have the same issue.
See this kernel bug report for more info:
https://patchwork.kernel.org/patch/2400621/
- Running the mainline kernel 3.9 rc8 resolves the issue.
