[LENOVO 7764CTO] suspend/resume failure

[Ken Tanzer]

This morning my laptop failed to resume after going to sleep following inactivity.

This had been working great on 9.04b. It generally worked on 8.10 too, but with 8.10 sometimes networking would be disabled after resuming, which has not been the case with 9.04b.

Sorry I'm really not able to give much details or clues. I know that suspend/resume is something you're looking hard at, though, so I'm reporting it anyway. It's a Thinkpad X61, and it was plugged into its docking station.

I also experience this issue. I experienced it with Fedora 10 as well. I run the 64-bit systems of both. From what I can tell, it has something to do with docking and undocking. If I do not dock the system, I can suspend and resume as much as I want. Same goes for when I boot it in the dock and leave it there, just suspending and resuming it. But, if I dock or undock the system will not resume.

in case anyone cares. it fails to resume most times (but not always) if it's been docked before it was suspended. I.e., laptop is docked; press undock button, wait for green light, remove from dock. syslog shows undocking works (usb instances disappear, Xorg notices changed video situation and adjusts, etc.) Laptop is now runinng undocked. Press fn-f4 to cause powermanager to trigger sleep. Laptop suspends. Try to resume --> screen powers up to text mode, blinking cursor, no X. (presumably it fails somewhere before the chvt back to the X screen) No disk access visible according to the disk activity LED. ctrl-alt-fN does not switch consoles. pushing power button does not run shutdown. keystrokes do not echo. Only recovery is to hold power button until hard power-off, then power back on.

Just an update. It does in fact fail to resume from suspend any time it has been docked since booting.

This bug was reported a while ago and there hasn't been any activity in
it recently. We were wondering if this is still an issue? Can you try
with the latest Karmic 9.10 release of Ubuntu? ISO CD images are
available from http://cdimage.ubuntu.com/releases/ .

If the issue remains, could you run the following command from a
Terminal (Applications->Accessories->Terminal) while running Karmic. It
will automatically gather and attach updated debug information to this
report.

apport-collect -p linux 355275

Thanks in advance
