I just tried mainline kernel 3.12.18-031218-generic for trusty - standby and resume work fine with this kernel version. So the bug seems to be new in 3.13.
Many laptops from different manufacturers show similar problems. They all use the snd_hda_intel kernel module but different codecs. -- 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/1305371 Title: [Dell Inspiron 1525] suspend/resume failure Status in “linux” package in Ubuntu: Confirmed Bug description: suspend/resume failed. restart required to bring back system ProblemType: KernelOops DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-23-generic 3.13.0-23.45 ProcVersionSignature: Ubuntu 3.13.0-23.45-generic 3.13.8 Uname: Linux 3.13.0-23-generic x86_64 Annotation: This occured during a previous suspend and prevented it from resuming properly.
