Long waiting time after resume from suspend-to-RAM

No ideas or solutions yet? Please let me know if I can somehow support you to fix this annoying bug. BTW: On the Dell Latitude D630 laptop, an error message "An unknown error occurred while Suspend to RAM. The errorcode is: '1'" is shown after unlocking the screen after resume. The window title is "Error while Suspend to RAM - KPowersafe". I have attached (the last part of) the log file /var/log/pm-suspend.log. Maybe this helps you to find the cause of the problem.

Since a bug in (K)Ubuntu made my Dell Latitude D630 laptop unusable (see my comments to bug #483359 and bug #483429), I re-installed Kubuntu 9.10 (Karmic). Luckily, the problem does not occur in the newly installed system. Since this issue (and a few other problems) occurred after upgrading from 9.04 (Jaunty) to 9.10 (Karmic) and does not occur in a freshly installed system, this problem is probably caused by a bug in the (dist-)upgrade procedure.

BTW: I originally installed Ubuntu 8.10 (Intrepid) on this computer, then changed to Kubuntu, and then upgraded to 9.04 (Jaunty). All this worked fine but I mention it here, because the upgrade to 9.10 (Karmic) might be affected by the previous upgrade. I have the non-working system still installed on another partition and the problem is still present on the Lenovo ThinkPad T400. So please let me know if you have any questions.

Unfortunately, I have the same problem on the newly installed system on my Dell Latitude D630 now :-( The problem came (back) in early December after updating ("apt-get upgrade") and rebooting the system. I reboot my laptop very seldom and I do not remember which updates I installed before I rebooted the system; IIRC, sreadahead and ureadahead where among them.

I found out something important: The problem occurs only if I suspend the laptop computers to RAM by closing the lid. However, if I click on the "K" button (KDE's "Kickoff Application Launcher"), choose "Leave" and "Sleep", wait a few seconds until I close the lid, and then resume it by opening the lid again, everything is okay and I can unlock the machine almost immediately.

Same problem here. I mind the long waiting time when resuming from RAM. It takes approx. 30-40 seconds, when suspending with closing the lid.

I forget to tell that I'm running Kubuntu Karmic on a Dell XSP1330 notebook.

Hi Oernie,

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 http://cdimage.ubuntu.com/releases/ .

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

apport-collect -p linux 483429

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 https://wiki.ubuntu.com/KernelMainlineBuilds . 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. Please let us know your results.

Thanks in advance.

I have still the same problem (Ubuntu 9.10, all updates). I will try what you suggested.

Same problem here, on a Lenovo X300 with kubuntu Lucid fresh install. I'll add the apport-collect info and I'll test the upstream kernel.

Seems to be fine (for now) with upstream kernel linux-image-2.6.35-999-generic_2.6.35-999.201006151505_amd64.deb on my Lenovo X300 with kubuntu Lucid Lynx.

I just tried again to suspend my laptop computer by closing the lid -- and I discovered that the problem has disappeared :-) Maybe one of the (kernel?) updated has solved this problem (see bve's comment #27). Thanks a lot for fixing this!

After testing now some days I realized, that normally with the new kernel (see #27) everything is fine, but as soon as wifi is on and I change the wifi-area, so that it has to search for new connections or looses it's last one, the login-screen comes up only after some 10 or 20 seconds. So it doesn't seem to be completely fixed...

Yes, the problem is not 100% fixed: Now I experience this problem no longer always but still sometimes. In contrast to bve (#29), it takes even longer until I can log in (up to 1 minute) on my computer (Dell Latidtude D630, Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)). I will check if this problem is related to wifi.

This bug was filed against a series that is no longer supported and so is being marked as Won't Fix. If this issue still exists in a supported series, please file a new bug.
