Public bug reported: I had this bug with kubuntu 11.10 and it is still present after upgrade to 12.04. I have an Asus 1215b laptop with Amd C60 cpu.
If I try to suspend the laptop, suspend seems to work at first, but then: 1) most of the times, the attempt to resume it brings to a black screen as a result. 2) After that, it is necessary to switch off the laptop by keeping the power button pressed. 3) Trying to switch on the laptop again produces a black screen and no boot, unless I first remove the power cord and the battery, and try again after putting them back in place. 4) Sometimes the first suspend attempt works correctly, but then, after a succesful resume, the second attempt reproduces the bug again. I tried the followings to see if it could help: 1) Changed from radeon driver to ATI proprietary fglrx driver, same result. 2) Installed the kernel 3.5.7 from http://kernel.ubuntu.com/~kernel-ppa/mainline, but I had problems with the fglrx ATI driver, and the first suspend and resume attempt immediatelly reproduced the bug Last, the bug has been present with all the kernel versions used with kubuntu 11.10 to current kernel version in Kubuntu 12.0.4.1: uname -r: 3.2.0-32-generic ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-32-generic 3.2.0-32.51 ProcVersionSignature: Ubuntu 3.2.0-32.51-generic 3.2.30 Uname: Linux 3.2.0-32-generic x86_64 NonfreeKernelModules: fglrx AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
