I can confirm that I've experienced this bug as well on a brand new
install of 17.04. Has happen twice when I leave the computer locked.
When I try to resume, monitors don't come up and I can't SSH in as well.
I'm testing 4.12.0-041200rc2-generic #201705212331 SMP Mon May 22
03:32:26 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux as suggested.
Here's the trace from syslog:
