It seems that this exactly problem is discussed here https://bugzilla.kernel.org/show_bug.cgi?id=41932 I referenced this bugreport there.
Reading through it revealed one more workaround: you can add "intel_idle.max_cstate=3" to kernel parameters. This will allow CPU to enter C1-C2 and suspend/resume will also work Also there is a patch (https://bugzilla.kernel.org/show_bug.cgi?id=41932#c22) which I was able to apply to kernel 3.6.1 and have the suspend problem fixed. I'm attaching it here just in case (for some reason the patch misses a closing bracket, had to add it by hand) ** Bug watch added: Linux Kernel Bug Tracker #41932 http://bugzilla.kernel.org/show_bug.cgi?id=41932 ** Patch added: "patch by Feng Tang" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1065076/+attachment/3394539/+files/new_s2ram.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1065076 Title: Lenovo S10-3 cannot wake up from suspend to RAM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1065076/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
