Bug Description

I have Lucid (10.04 LTS) installed to two Lenovo Thinkpads 7764-CTO.
Both video and wifi are Intel parts. Neither will suspend-to-ram (sleep).

I expect the following:

shutdown-like tinkering
blinking moon LED
power-down behavior leaving the moon LED lit
On Wake: immediate display of "locked session" login page

Using the GNOME panel, I select "Suspend" ==> suspend-to-ram (aka, "sleep") It fiddles then crash with the moon-LED blinking. On wake, it does not show any signs of a "restart".

I have an open case #13444 within Landscape at Canonical Support.

There are attached log files with that case that might offer diagnostic value when
considering this bug report.

Merci d'avance,

Dan confirmed that this system suspends as expected when using Ubuntu 10.10 64-bit.

I'll be summarizing our findings in this bug report as we progress, if anyone else has this hardware I'd appreciate any reports on how suspend / hibernate work (or don't) in 10.04.1 LTS or 10.10.

This laptop has a built-in SD/SDHC media reader. (I'm not sure what to report and post -- other than what 'spider' says already -- that will identify the hardware and driver specifics.)

I wrote a script that will simply un-mount anything mounted to /media/* at the time of any sort of suspend request.
With that script in place, both suspend-to-disk and suspend-to-ram mostly work.

"Mostly" works stems from the fact that other connected USB or FIREWIRE items sometimes result in failure.
I have not discovered scripting that will automatically detect these other devices and accomplish an automatic
un-mount equivalent.

When the end-user requests suspend using keystroke or button or panel menu option, manual "evasive" or "corrective"
action is possible. When power-management or acpi requests the suspend, manual intervention is not possible and one
must recover from a panic or other system failure (locked-up, running but not responding, etc)

Resume also "mostly works". I continue to experience intermittent failures to wake and restart wireless networking
(Intel 4965 AGN), wire networking (Intel 82566MM) and to wake and restart all aspects of the desktop (Intel GM965/GL960).
Resume failures include:
** wireless radio turned off and does not turn on with wake
(sometimes cycle hardware radio power switch to recover; otherwise system restart.)
** any attempt to contact the public internet fails with DNS or other server troubles
(restart required)
** desktop keyboard does not accept input requiring
(sometimes x-server restart will recover; otherwise system restart.)

Saint DanBert, 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 development release of Ubuntu? ISO CD images are available from .

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

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.
