Public bug reported: Suspend works unreliably, failing sometimes.
When suspend works, the following reboot will fail, with a blank screen with a cursor after the BIOS splash screen. It seems to be trying to access the hard drive for booting, but fails, eventually showing the error of no valid boot media present. Taking out AC power and battery solves the issue, until the next time you try to suspend... I have tried the procedure for debugging suspend, but I could not identify any device ID in the dmesg output, after the "Magic number" line. https://wiki.ubuntu.com/DebuggingKernelSuspend ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-24-generic 3.2.0-24.39 ProcVersionSignature: Ubuntu 3.2.0-24.39-generic 3.2.16 Uname: Linux 3.2.0-24-generic i686 NonfreeKernelModules: wl AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
