**It seems the problem starting with kernel 3.18** Ok, so next I installed http://download.opensuse.org/repositories/home:/tiwai:/kernel:/3.18/standard/ and the boot issue started hapening. Out of 7 attempts, 5 failures ans 2 successes. I am attaching dmesg from 3.18 (after a succesful boot) and also differences between 3.18 (left) and 3.17 (right). There are number of interesting things in 3.18 dmesg that do not exist in 3.17 but I have no idea about their significance. What can we do next?
