I could not get linux-image-3.13.0-5-generic to work on saucy. Xorg would not register my video card correctly.
I've now patched 3.11.0-15-generic and I've been using the system as such since Thursday. Yesterday I encountered a hang of the wifi driver just after joining a torrent, which had a lot of peers/seeds, in deluge. Unfortunately, I have not found any panic message (and I've confirmed ath9k_htc.ko was patched correctly). I could not recover from this state. suspend did not work and I could not disconnect using network manager.
