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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1305371 Title: [Dell Inspiron 1525] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1305371/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
