Title:
  15.04 with 3.19.0-17 kernel boot failure

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  An Acer Aspire 5920 with Ubuntu 15.04 kernel 3.19.0-17-generic fails boot up going unresponsive very early in the sequence.
  I installed the upstream kernel packages on my Acer Aspire 5920 laptop:
  linux-headers-4.1.0-040100rc2-generic_4.1.0-040100rc2.201505032335_amd64.deb
  linux-image-4.1.0-040100rc2-generic_4.1.0-040100rc2.201505032335_amd64.deb
  The machine booted successfully 3 times with warnings about installed packages having unmet dependencies.
  uname -r command confirmed that the expected kernel was running: 4.1.0-040100rc2-generic
