I'd like to delete my previous two comments because on a second Suspend under 3.13.0-32 the laptop resumed immediately and led to a system crash again. However I'm loath to delete what's already been written.
A few months whilst still running Windows 7 ago I changed the BIOS to wake on USB activity for a now shelved project for the UPS triggered USB interrupt to send out an e-mail that the power has gone off. It turns out syslog under Ubuntu is now being spammed with the message: "hub 4-0:1.0: Cannot enable port 3. Maybe the USB cable is bad?" Turning off the BIOS option to wake up on USB fixed the problem with immediate Resume after Suspend followed by crash in Ubuntu. I don't have Windows 7 reinstalled yet to see if the same happens there. My apologies to those I mislead based on one-time test results. The new test results have proven true 3 times so far :). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1550351 Title: [Asus P8Z68-V LX] suspend/resume failure Status in linux package in Ubuntu: Incomplete Bug description: Got crash message upon booting after update.
