Comment 10 for bug 1787191

I'm using Ubuntu 14.04.5 LTS \n \l , after patching kernel linux-generic to 3.13.0.155 and intel microcode to 3.20180425.1~ubuntu0.14.04.2 , i reboot to apply the patches and the system freeze after booting, CPU is Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz , there is a kernel or microcode bug? after role back to oldest version it went normal
Does the newest version available of kernel and intel microcode fixed those bugs?
