I have tested 3.17.1-031701-generic. The bug is still there, but things are worse. If I boot with the lid open, close the lid and log out, I get a black screen. I got the lightdm login after I pressed several keys, including Ctrl-Alt-Delete. I was able to log in, but things were very sluggish. I got many error messages from apport. The network was down, I could not use su. After rebooting, I found that one of the error messages was about a kernel oops, another was about a crash in lightdm. There were many more messages.
