Hi all, just to give some feedback on the 3.17 testing proposal: I'm also affected by the bug reported here (no kvm, both with old and updated BIOS) for 3.16.x utopic kernels, the problem "appeared" after short uptimes of usually 1..2 day.
Now I'm running a 3.17 kernel without a crash for 14 days. No idea if the bug is really fixed but the system usability has improved significantly by the absence of such crashs ;-) Please let me also express that I'd consider the importance of this bug higher than medium since many Ultrabooks/Notebooks/etc. come with embedded i915 graphics today. BR and thanks!

Either way, my system hard-locked.
