I switched to Arch, where the problem persists. The rc.local fix described above does not work because Arch uses systemd. Here is a UDEV rule that solves the problem.
# cat /etc/udev/rules.d/ehc1.rules ACTION=="add", KERNEL=="0000:00:1d.0", SUBSYSTEM=="pci", RUN+="/bin/sh -c 'echo EHC1 > /proc/acpi/wakeup'" From: https://bbs.archlinux.org/viewtopic.php?pid=1393073#p1393073 Apparently, even macs are having this problem, the root of which is the EHC1 USB device controller wakeing the computer - sometimes randomly. This bug is rather bad because it can cause the laptop to wake while inside an enclosed insulated space, like a backpack, which makes things get very hot in there. I have little hope that the latest Thinkpad Bios will resolve this problem, but will try to test in the coming weeks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1309938 Title: [Thinkpad Twist] resumes immediately after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1309938/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
