Confirm same issue with Dell Inspiron N5110 -- Core i7 Sand Bridge Mobile. Xubuntu 12.04. Tried all kernels from 3.2 through 3.5rc1. Same issue.
Rebuilt all Intel drivers from git source -- same issue. NOT using Compiz KERNEL panics from iwlwifi/mac80211 fixed after recompiling. NOT using Gnome or Gnome Shell or unity. Using Bumblebee for Optimus graphics. libva vaapi working beautifully. vdpau not working? I will try "i915.i915_enable_rc6=0" boot flag from above, and see how I go. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
