I have the same problem with my Dell inspiron 1525 and Ubuntu 14.04. with kernel 3.13.0-24 generic x86. The kernel oops seems to be caused by the kernel module snd_hda_intel. Resuming from standby works in most cases with a standby hook which kills pulseaudio and unloads the module snd_hda_intel before standby and reloads snd_hda_intel after resume. See attached file. In some cases the computer doesn't go to standby when I close the lid. When I reopen it, the display remains black and the computer doesn't respond. So this workarround is not reliable.
I updated from Ubuntu 13.10, the Saucy kernel 3.11.0-19-generic remained installed. When I boot Ubuntu 14.04 with this kernel, standby and resume work fine (of course without the standby hook mentioned above). ** Attachment added: "standby hook" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1305371/+attachment/4102685/+files/00_snd_hda_intel -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
