at #15: one time boot with 3.19.0-17: added 'drm.debug=0xe' to the boot options, removed "quiet no splash". Boot attempt with 3.19.0-17 was made at 10:56, I suppose.
Later, successfully booted was with 4.0. Included /var/log/kern.log. ** Attachment added: "boot attempt with 3.19.0-17" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1453593/+attachment/4397993/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1453593 Title: 3.19.0-17 freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1453593/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
