Public bug reported: Most of the time with my Toshiba laptop, suspend/resume works OK. However, sometimes (around 1 time in 4) suspend fails (during going to sleep) with the following symptoms:
- Screen goes dark, backlight off - Screen remains blank, backlight comes back on - No flashing caps or num lock - Increased fan activity after approx 10 seconds - Ctrl+Alt+Del , Ctrl+Alt+F1, short press on power button, REISUB all have no effect. - Only way to recover system is to hold down power button. Suspending from the console using sudo pm-suspend does generate some text, unfortunately, it appears on the screen too briefly to take a photo. I will attach dmesg and pm-suspend logs shortly. This did work in the past, however, it was some time (and several kernel versions) ago. With the -12 dbgsym kernel installed, I was able to run locatehang, which returned: $ sudo ./locatehang [sudo] password for charlie: Looking for function that matches hash from the Magic Number from the kernel log. Magic: 3:476:552 maps to hash: 867a43 Hash matches: disable_nonboot_cpus() (address: ffffffff81060790) However, manual offlining following advice from the below thread did not seem to help. http://ubuntuforums.org/showthread.php?t=1892647&page=2 ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: linux-image-3.0.0-16-generic 3.0.0-16.29 ProcVersionSignature: Ubuntu 3.0.0-16.29-generic 3.0.20 Uname: Linux 3.0.0-16-generic x86_64 NonfreeKernelModules: nvidia wl AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
