Similarly Brad's findings I also confirm, that upgrade to kernel 4.8 actually made things worse in my configuration. Now the system is broken not after second suspend, but right after the first suspend and resume. The screen comes back on, but keyboard and mouse are dead, visible processes are dead (no way to type ps, but clock and other visible things in X windows are not updating). Requires hard reboot.
To recap my configuration: Lenovo S435 UEFI mode BIOS upgraded to BBCN16WW(V1.07) Debian Stretch (testing) kernel 4.8.0-1-amd64 #1 SMP Debian 4.8.5-1 (2016-10-28) x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1528735 Title: Suspend fails every second time on some laptops in UEFI mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1528735/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
