Comment 11 for bug 1210858

Combat, thank for posting the Lucid logs, as it did help immensely in revealing the true root cause. In your current Saucy install, could you please add to your kernel boot parameters the following:
irqpoll

One may do this via a terminal:
sudo gedit /etc/default/grub

and change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash irqpoll"

execute at a terminal:
sudo update-grub

restart your computer, and advise if anything changes.
