Björn Schließmann, 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? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-3.23 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/623550 Title: Computer often freezes while entering hibernation since maverick alpha Status in The Linux Kernel: Expired Status in “linux” package in Ubuntu: Incomplete Bug description: Since trying out Maverick Alpha, my Thinkpad T41 quite often (approx. 5 out of 10 times) freezes while entering hibernation mode. It always happens at the same stage. When hibernating successfully, this happens: 1. session gets locked, screen black, backlight on 2. VT appears, "moon" LED starts blinking 3. Backlight is turned off, "moon" LED blinks 4. Backlight is turned on again, "moon" LED off, HD saves memory contents 5. Computer turns off. When the bug hits, computer hangs at step 3. (I once waited for some 15 minutes, nothing else happened.) /var/log/pm-suspend.log always ends with lines like these: Tue Aug 24 20:46:55 CEST 2010: performing hibernate I turned on pm_trace; the hw clock is set but after booting, there is *never* a "hash matches" entry in dmesg output. I tested several mainline kernels (last is 2.6.36-999.201008190908), all show the same behaviour.
