I tested the v4.6-rc6-wily mainline kernel from http://kernel.ubuntu.com /~kernel-ppa/mainline/v4.6-rc6-wily/ and that fixes the problem, suspend-resume works without freezing! I repeated the suspend-resume cycle five times without problems.
The kernel is: 4.6.0-040600rc6-generic #201605012031 SMP Mon May 2 00:33:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux Adding kernel-fixed-upstream tag as suggested in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1570484/comments/3 ** Tags added: 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/1578650 Title: Lenovo X1 Carbon 4th freezes after suspend-resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1578650/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
