365c483f190fea03971b3eca8d68406f425777b5 works fine but there is something other very interesting: This kernel has an extreme performance boost in booting time on my system. It boots now about 2-3 seconds faster (~10-15%) compared to the working kernels. Normally I have noticed within the last months that the kernel booting time in generic got slower. What is the difference of this compiled kernel compared to the others in the official repository and http://kernel.ubuntu.com /~kernel-ppa/mainline/ ?

I'm noticing that now on every boot my hard disk will stop multiple times for a short time and logging out from the console does sometimes hang a few seconds. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version k3.15.0-5-generic.
