I have a Lenovo Carbon X1 4th Gen which is most of the time connected to a OneLink+ dock. I encounter the same problem with kernel 4.4.0-22: Resume sometimes works, but sometimes not.
I have tested a few of the recent kernels available on https://kernel.ubuntu.com/~kernel-ppa/mainline/ and here are my results: Not booting with Ubuntu 16.04 on Lenovo Carbon X1 4th Gen: - drm-intel-next/2016-06-02-yakkety/linux-image-4.6.0-997-generic_4.6.0-997.201606012202_amd64.deb - drm-next/2016-06-03-yakkety/linux-image-4.7.0-996-generic_4.7.0-996.201606022202_amd64.deb Boots but fails to resume on 1st try: - drm-next/2016-05-09-wily/linux-image-4.6.0-996-generic_4.6.0-996.201605082201_amd64.deb Resumes fine: - drm-intel-nightly/2016-06-05-yakkety/linux-image-4.7.0-994-generic_4.7.0-994.201606042201_amd64.deb - daily/2016-06-05-yakkety/linux-image-4.7.0-999-generic_4.7.0-999.201606042201_amd64.deb In both cases I've made a few resumes and also plugged the dock on and off several times without any issues so far. Currently I'm running the latest daily kernel and it seems to work good. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1566302 Title: Ubuntu 16.04: Suspend freezes the system after upgrade to linux image 4.4.0-16 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1566302/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
