It always happens while booting before the login screen appears. Most confusing is, sometimes the laptop boots without any problems. The next day I have to start it like 5 times before I am able to login.
It happend with Ubuntu 15.04 as well and I hoped it will go away with 15.10 but it did not.
Before I had Linux Mint 16 installed and never experienced that error.
I suppose it is while loading some kernel module but I do not know how to read the kernel logs to debug this problem.
I appreciate any help.
