Bug Description
Hello.
It seems, that 'kaslr' option is responsible for issues with system booting. The latest working kernel is v4.4.0-112.135. Every next release: v4.4.0-113.136 and v4.4.0-115.139 are unable to boot if 'kaslr' option is in use etc. Everything is described in my previous bug report (please see 1.), but I've decided to create a new one, because it seems, that some of the "Spectre & Meltdown" patches are not compatible with kASLR and are responsible for this regressions.
Thanks, best regards.

Hello. It seems, that everything is okay now and 'kaslr' option is working again. After update Linux kernel to the v4.4.0-117-generic (v4.4.114) version, system boots normally. So, some of the patches (see 1.) fixed this issue.
