Title:
Unity(7) freezes completely after Kernel update (3.18.0.9.9) on intel
GMA-965 (Vivid)
Status in compiz package in Ubuntu:

Status in linux package in Ubuntu:
Incomplete
Bug description:
After I update the kernel to 3.18.0.9.9, Unity freezes few minutes
after login on Vivid. This happens for any compiz based session like
gnome-flashback(compiz). I tried booting with both the systemd &
upstart from boot menu, but the outcome did not change. Ctrl+Alt+F1 or
Alt+SysRq does not work after freeze.
Just before the freeze syslog prints following error:

I have attached the complete syslog.txt & xorg.txt
(http://paste.ubuntu.com/9852608/) for the session.
It could also be a bug in kernel, however It does not crash at all on
non-compiz session like Gnome-Flashback (Metacity).
