Comment 2 for bug 1085245

After installing this kernel on a new dell xps 13 (ivy bridge version), unity always freezes after a resume from suspend. The mouse still moves and I can switch to VT1 to reboot. Reverting to 3.5.0-19 resolves the problem. Not sure if the freeze is due to the introduction of haswell support or other upstream kernel changes (i.e. bug #1084539).
