Same here, but the couple of working/non-working kernel is
3.5.0-25/3.5.0-26.

My hardware is a Dell Inspiron N7110 with a i7-2670QM CPU and a NVIDIA
GeForce GT 540M disabled using bbswitch :

[   46.492299] bbswitch: version 0.6
[   46.492305] bbswitch: Found integrated VGA device 0000:00:02.0:
\_SB_.PCI0.GFX0
[   46.492309] bbswitch: Found discrete VGA device 0000:01:00.0:
\_SB_.PCI0.PEG0.PEGP
[   46.492508] bbswitch: detected an Optimus _DSM function
[   46.492513] bbswitch: disabling discrete graphics
[   46.610983] bbswitch: Succesfully loaded. Discrete card 0000:01:00.0 is off
