Here's my latest test result, using: - X220 i7 - Samsung 840 Pro SSD - BIOS 1.39 - Ubuntu 12.04.3 - Kernel 3.8.0-33
Using "sudo pm-suspend", the first cycle completes normally. On the second cycle, I see an "Unable to dock!" message as it's suspending. It resumes to show a black screen with the "Unable to dock" message on it. I use can "Alt-F1" to see a screen with a login prompt, but I can't login. After a hard-power-off and restarting, I check /var/log/pm-suspend.log and find that the last suspend is logged, but there is no detail at all about resume. The only indication of a problem I see in /var/log/pm-suspend.log is "Having NetworkManager put all interfaces to sleep...Failed", but that happens on the first, successful suspend cycle as well. >From having looked at other variations of this issue as I've tried to work through it, I think what's happening is that the OS is running after resume, but I/O to the hard drive has failed. That explains why the "resume" portion of the logging is completely missing, and why I can get as far as the login screen, but login (presumably it's started to load something from the drive at that point, and is failing). In the BIOS, I tried changing the SATA connection from "AHCI" to Legacy, but it doesn't help. (Above it's in Legacy mode still, I think). I also tried an Intel 520 Cherryville SSD with similar results. Using a mechanical Hitachi drive, I was able to 10 successful suspend/resume cycles in a row, but I want this to work with one of these two SSDs. As noted above, I also tried 14.04 on this laptop, and had problems with suspend as well. My last notes on that contain a different failure mode, though: " Suspended via Fn-F4, Screen came back, but was very dim, and mouse was frozen." I'm willing to try either 12.04 or 14.04, if you have suggestions of things to try. 12.04 is currently on the SSD, while 14.04 is on a Live USB drive. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1233794 Title: [LENOVO ThinkPad X220] suspend/resume failure Status in “linux” package in Ubuntu: Incomplete Bug description: It seem to me that this is a strange problem.
