Title:
very long kernel boot time with some KVM switch
Status in linux package in Ubuntu:
Incomplete
Bug description:
I am using a Aten KVM switch CS1794 hooked on my computer.
It allows the switching for USB, HDMI, and audio.
http://www.aten.com/global/en/products/kvm/desktop-kvm-switches/cs1794/#.WWrnguk9iUk
I run a Ubuntu 17.04 system.
I experience a very long boot time, having done an analysis it appears
that the main problem is the kernel boot time and more specifically
the time it takes to start its USB subsystem.
when you look at the dsmg output you can clearly see a gap between
4-78s and 79-91s, all in the USB sub-process.
