Suspend regression on Kernel 5.0

[Ramil Minnigaliev]

After you turn on suspend mode, the system freezes. Does not respond to Ctrl+Alt+F1... And even the logs are not saved to disk. There is nothing in the log after switching to suspend mode, although I immediately try to wake up the system.

With kernel 4.18 I have not this problem.

Ubuntu 18.04.3
