Sorry for not explaining clearly. Testing of the upstream kernel did originally work but the kernel that was tested had some DKMS drivers that would not load:
[code] Consult /var/lib/dkms/bbswitch/0.7/build/make.log for more information. Consult /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/make.log for more information. Consult /var/lib/dkms/vboxhost/5.0.4/build/make.log for more information. Consult /var/lib/dkms/nvidia-346/346.59/build/make.log for more information. [/code] The original upstream kernel that was tested was version 3.19.31, when that kernel made it in to the distro, the problem was not fixed. I have since tested mainline kernel 4.2.5, and the problem also is not fixed. So the mainline kernel does not fix the problem. I hope this is clearer. ** Tags removed: kernel-fixed-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1495043 Title: Suspend/Resume Regression 3.19.0-28-generic Dell xps15 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1495043/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
