Resume from hibernation does not working since 3.13.0-74

[Pali]

My laptop Dell Latitude E6440 is not able to resume from hibernation on linux kernel version 3.13.0-74. Version 3.13.0-71 is last working. When I try to resume on version 3.13.0-74 it just show bootlog, then reading resume image. And after resume image is loaded, screen goes black and laptop do nothing. Network is not working, so I cannot connect to laptop. Even enabled SYSRQ keys do not work. Hard shutdown with power button is needed. After next boot there is nothing about last failed resume in syslog, so I do not have any information for debugging.

I tested v4.4-rc6-wily and hibernation is working fine.

Nope, this bug affects *only* linux-lts-trusty package found in Ubuntu
Precise. Bug was introduced in linux-lts-trusty. So why removed it from
package list?
