FYI. I am hit by this problem too. Updated system in Synaptic on 26th which included Upgrade: amd64-microcode:amd64 (2.20131007.1+really20130710.1, 3.20180524.1~ubuntu0.14.04.1)
Had previously installed (2 weeks ago) linux-image- extra-3.13.0-151-generic:amd64 (3.13.0-151.201) Now system hangs with black screen. Running in recovery mode the last two lines are x86: Booting SMP configuration: .... node #0: CPUs #1 Booting back in 3.13.0-149 works fine. smpboot: CPU0: AMD Athlon(tm) II X4 600e Processor (fam: 10, model: 05, stepping: 02) Gigabyte Technology Co., Ltd.
