I'm using Ubuntu 14.10 dev with linux-image-generic 3.16.0.9.10 and as already mentioned in the other ticket (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1325819) I'm noticing a performance loss in booting time of a few seconds with newer versions of the kernel. But interestingly one linked kernel in the other ticket (http://kernel.ubuntu.com/~jsalisbury/lp1325819/ -> 3.13.0-031300rc3-generic) doesn't have this problem. In the attachments are 2 dmesg logs of the different kernels. As they show the 3.13.0-031300rc3-generic was ~2 seconds faster with loading the nvidia module (last lines in dmesg) than the current kernel. I'm wondering why there is this difference between those kernels in booting time.
